# PowerToy DLL Project For Visual Studio 2019
|
|
|
|
## Installation
|
|
|
|
- Put the `ModuleTemplate.zip` file inside the `%USERPROFILE%\Documents\Visual Studio 2019\Templates\ProjectTemplates\` folder, which is the default *User project templates location*. You can change that location via `Tools > Options > Projects and Solutions`.
|
|
- The template will be available in Visual Studio, when adding a new project, under the `Visual C++` tab.
|
|
|
|
## Contributing
|
|
If you'd like to work on a PowerToy template, make required modifications to `\tools\project_template\ModuleTemplate.vcxproj` and then use the dedicated solution `PowerToyTemplate.sln` to export it as a template. Note that `ModuleTemplate.vcxproj` is actually a project template, therefore uncompilable, so we also have a dedicated `ModuleTemplateCompileTest.vcxproj` project referenced from the `PowerToys.sln` to help keeping the template sources up to date and verify it compiles correctly.
|
|
|
|
## Create a new PowerToy Module
|
|
|
|
- Add the new PowerToy project to the `src\modules\` folder for all the relative paths to work.
|
|
- For the module interface implementation take a look at [the interface](/src/modules/interface).
|
|
- Each PowerToy is built as a DLL and in order to be loaded at run-time, the PowerToy's DLL name needs to be added to the `known_dlls` map in [src/runner/main.cpp](/src/runner/main.cpp).
|
|
|
|
## DPI Awareness
|
|
|
|
All PowerToy modules need to be DPI aware and calculate dimensions and positions of the UI elements using the Windows API for DPI awareness.
|
|
The `/src/common` library has some helpers that you can use and extend:
|
|
- [`dpi_aware.h`](/src/common/dpi_aware.h), [`dpi_aware.cpp`](/src/common/dpi_aware.cpp)
|
|
- [`monitors.h`](/src/common/monitors.h), [`monitors.cpp`](/src/common/monitors.cpp)
|
|
|
|
## PowerToy settings
|
|
|
|
### Settings architecture overview
|
|
|
|
PowerToys provides a settings infrastructure to add a settings page for new modules. The PowerToys Settings application is accessed from the PowerToys tray icon, it provides a global settings page and a dedicated settings page for each module.
|
|
|
|
The PowerToys settings API provides a way to define the required information and controls for the module's settings page and methods to read and persist the settings values. A module may need a more complex way to configure the user's preferences, in that case it can provide its own custom settings editor that can be invoked from the module's settings page through a dedicated button.
|
|
|
|
The settings specification can be read at [doc/specs/PowerToys-settings.md](/doc/specs/PowerToys-settings.md).
|
|
|
|
A PowerToy can provide this general information about itself:
|
|
- **[name](#name)**: The name of the PowerToy.
|
|
- **[description](#description)**: A text describing the PowerToy.
|
|
- **[icon_key](#icon_key)**: The identifier of the PowerToy icon in the [`settings-web` project](/src/settings-web#updating-the-icons).
|
|
- **[overview_link](#overview_link)**: A link to an extended overview of the PowerToy.
|
|
- **[video_link](#video_link)**: A link to a video showcasing the PowerToy.
|
|
|
|
A PowerToy can define settings of the following types:
|
|
- **[bool_toggle](#bool_toggle)**: A boolean property, edited with a Toggle control.
|
|
- **[int_spinner](#int_spinner)**: An integer property, edited with a Spinner control.
|
|
- **[string](#string)**: A string property, edited with a TextBox control.
|
|
- **[color_picker](#color_picker)**: A color property, edited with a ColorPicker control.
|
|
- **[custom_action](#custom_action)**: A custom action property, invoked from the settings by a Button control.
|
|
|
|
Here's an example of what the settings look like in the Settings screen:
|
|
|
|
|
|
|
|
### How to add your module's settings page
|
|
|
|
The PowerToy can set its settings information and controls by overriding the [PowerToy's Interface `get_config` method](/src/modules/interface/README.md#get_config) and returning a serialized [`PowerToysSettings::Settings`](/src/common/settings_object.h) object that's been filled with the required information and controls.
|
|
|
|
The PowerToy can receive the new values by overriding the [PowerToy's Interface `set_config` method](/src/modules/interface/README.md#set_config), parsing the serialized [`PowerToysSettings::PowerToyValues`](/src/common/settings_object.h) object and applying the new settings.
|
|
|
|
Here's an example settings implementation:
|
|
```cpp
|
|
// Return JSON with the configuration options.
|
|
virtual bool get_config(wchar_t* buffer, int* buffer_size) override {
|
|
HINSTANCE hinstance = reinterpret_cast<HINSTANCE>(&__ImageBase);
|
|
|
|
// Create a Settings object.
|
|
PowerToysSettings::Settings settings(hinstance, get_name());
|
|
settings.set_description(L"Serves as an example powertoy, with example settings.");
|
|
|
|
// Show an overview link in the Settings page
|
|
settings.set_overview_link(L"https://github.com/microsoft/PowerToys");
|
|
|
|
// Show a video link in the Settings page.
|
|
settings.set_video_link(L"https://www.youtube.com/watch?v=d3LHo2yXKoY&t=21462");
|
|
|
|
// Add a bool property with a toggle editor.
|
|
settings.add_bool_toggle(
|
|
L"test_bool_toggle", // property name.
|
|
L"This is what a BoolToggle property looks like", // description or resource id of the localized string.
|
|
g_settings.test_bool_prop // property value.
|
|
);
|
|
|
|
// Add an integer property with a spinner editor.
|
|
settings.add_int_spinner(
|
|
L"test_int_spinner", // property name
|
|
L"This is what a IntSpinner property looks like", // description or resource id of the localized string.
|
|
g_settings.test_int_prop, // property value.
|
|
0, // min value.
|
|
100, // max value.
|
|
10 // incremental step.
|
|
);
|
|
|
|
// Add a string property with a textbox editor.
|
|
settings.add_string(
|
|
L"test_string_text", // property name.
|
|
L"This is what a String property looks like", // description or resource id of the localized string.
|
|
g_settings.test_string_prop // property value.
|
|
);
|
|
|
|
// Add a string property with a color picker editor.
|
|
settings.add_color_picker(
|
|
L"test_color_picker", // property name.
|
|
L"This is what a ColorPicker property looks like", // description or resource id of the localized string.
|
|
g_settings.test_color_prop // property value.
|
|
);
|
|
|
|
// Add a custom action property. When using this settings type, the "PowertoyModuleIface::call_custom_action()"
|
|
// method should be overridden as well.
|
|
settings.add_custom_action(
|
|
L"test_custom_action", // action name.
|
|
L"This is what a CustomAction property looks like", // label above the field.
|
|
L"Call a custom action", // button text.
|
|
L"Press the button to call a custom action in the Example PowerToy" // display values / extended info.
|
|
);
|
|
|
|
return settings.serialize_to_buffer(buffer, buffer_size);
|
|
}
|
|
|
|
// Called by the runner to pass the updated settings values as a serialized JSON.
|
|
virtual void set_config(const wchar_t* config) override {
|
|
try {
|
|
// Parse the input JSON string.
|
|
PowerToysSettings::PowerToyValues values =
|
|
PowerToysSettings::PowerToyValues::from_json_string(config);
|
|
|
|
// Update the bool property.
|
|
if (values.is_bool_value(L"test_bool_toggle")) {
|
|
g_settings.test_bool_prop = values.get_bool_value(L"test_bool_toggle");
|
|
}
|
|
|
|
// Update the int property.
|
|
if (values.is_int_value(L"test_int_spinner")) {
|
|
g_settings.test_int_prop = values.get_int_value(L"test_int_spinner");
|
|
}
|
|
|
|
// Update the string property.
|
|
if (values.is_string_value(L"test_string_text")) {
|
|
g_settings.test_string_prop = values.get_string_value(L"test_string_text");
|
|
}
|
|
|
|
// Update the color property.
|
|
if (values.is_string_value(L"test_color_picker")) {
|
|
g_settings.test_color_prop = values.get_string_value(L"test_color_picker");
|
|
}
|
|
|
|
// If you don't need to do any custom processing of the settings, proceed
|
|
// to persists the values calling:
|
|
values.save_to_settings_file();
|
|
// Otherwise call a custom function to process the settings before saving them to disk:
|
|
// save_settings();
|
|
}
|
|
catch (std::exception ex) {
|
|
// Improper JSON.
|
|
}
|
|
}
|
|
```
|
|
|
|
### Settings Informations
|
|
The PowerToys settings object supports adding additional information to a PowerToys Settings description:
|
|
|
|
#### name
|
|
The name of the PowerToy. Its a required information that's applied in the settings object constructor:
|
|
|
|
```cpp
|
|
PowerToysSettings::Settings settings(hinstance, get_name());
|
|
```
|
|
|
|
#### description
|
|
A short description of the PowerToy.
|
|
|
|
```cpp
|
|
settings.set_description(L"Serves as an example powertoy, with example settings.");
|
|
```
|
|
or
|
|
```cpp
|
|
settings.set_description(description_resource_id);
|
|
```
|
|
where `description_resource_id` is the UINT index of a resource string in the project .rc file.
|
|
|
|
#### icon_key
|
|
The identifier of the PowerToy icon in the [`settings-web` project](/src/settings-web#updating-the-icons).
|
|
By default, a `CircleRing` icon from *FabricUI* is shown for the PowerToy if no icon is specified.
|
|
|
|
```cpp
|
|
settings.set_icon_key(L"pt-shortcut-guide");
|
|
```
|
|
|
|
#### overview_link
|
|
A link to an extended overview of the PowerToy.
|
|
```cpp
|
|
settings.set_overview_link(L"https://github.com/microsoft/PowerToys");
|
|
```
|
|
|
|
|
|
#### video_link
|
|
A link to a video showcasing the PowerToy.
|
|
|
|
```cpp
|
|
settings.set_video_link(L"https://www.youtube.com/watch?v=d3LHo2yXKoY&t=21462");
|
|
```
|
|
|
|
### Setting Controls
|
|
|
|
#### bool_toggle
|
|
|
|
A boolean property, edited with a Toggle control.
|
|
|
|
It can be added to a `Settings` object by calling `add_bool_toggle`.
|
|
```cpp
|
|
// Add a bool property with a toggle editor.
|
|
settings.add_bool_toggle(
|
|
L"test_bool_toggle", // property name.
|
|
L"This is what a BoolToggle property looks like", // description or resource id of the localized string.
|
|
g_settings.test_bool_prop // property value.
|
|
);
|
|
```
|
|
|
|
It can be read from a `PowerToyValues` object by calling `get_bool_value`.
|
|
```cpp
|
|
// Update the bool property.
|
|
if (values.is_bool_value(L"test_bool_toggle")) {
|
|
g_settings.test_bool_prop = values.get_bool_value(L"test_bool_toggle");
|
|
}
|
|
```
|
|
|
|
#### int_spinner
|
|
|
|
An integer property, edited with a Spinner control.
|
|
|
|
It can be added to a `Settings` object by calling `add_int_spinner`.
|
|
```cpp
|
|
// Add an integer property with a spinner editor.
|
|
settings.add_int_spinner(
|
|
L"test_int_spinner", // property name
|
|
L"This is what a IntSpinner property looks like", // description or resource id of the localized string.
|
|
g_settings.test_int_prop, // property value.
|
|
0, // min value.
|
|
100, // max value.
|
|
10 // incremental step.
|
|
);
|
|
```
|
|
|
|
It can be read from a `PowerToyValues` object by calling `get_int_value`.
|
|
```cpp
|
|
// Update the int property.
|
|
if (values.is_int_value(L"test_int_spinner")) {
|
|
g_settings.test_int_prop = values.get_int_value(L"test_int_spinner");
|
|
}
|
|
```
|
|
|
|
#### string
|
|
|
|
A string property, edited with a TextBox control.
|
|
|
|
It can be added to a `Settings` object by calling `add_string`.
|
|
```cpp
|
|
// Add a string property with a textbox editor.
|
|
settings.add_string(
|
|
L"test_string_text", // property name.
|
|
L"This is what a String property looks like", // description or resource id of the localized string.
|
|
g_settings.test_string_prop // property value.
|
|
);
|
|
```
|
|
|
|
It can be read from a `PowerToyValues` object by calling `get_string_value`.
|
|
```cpp
|
|
// Update the string property.
|
|
if (values.is_string_value(L"test_string_text")) {
|
|
g_settings.test_string_prop = values.get_string_value(L"test_string_text");
|
|
}
|
|
```
|
|
|
|
#### color_picker
|
|
|
|
A color property, edited with a ColorPicker control. Its value is a string with the `'#RRGGBB'` format, with two hexadecimal digits for each color component.
|
|
|
|
It can be added to a `Settings` object by calling `add_color_picker`.
|
|
```cpp
|
|
// Add a string property with a color picker editor.
|
|
settings.add_color_picker(
|
|
L"test_color_picker", // property name.
|
|
L"This is what a ColorPicker property looks like", // description or resource id of the localized string.
|
|
g_settings.test_color_prop // property value.
|
|
);
|
|
```
|
|
|
|
The `'#RRGGBB'`-format string can be read from a `PowerToyValues` object by calling `get_string_value`.
|
|
```cpp
|
|
// Update the color property.
|
|
if (values.is_string_value(L"test_color_picker")) {
|
|
g_settings.test_color_prop = values.get_string_value(L"test_color_picker");
|
|
}
|
|
```
|
|
|
|
#### custom_action
|
|
A custom action property, invoked from the settings by a Button control. This can be used to spawn a custom editor by the PowerToy.
|
|
|
|
It can be added to a `Settings` object by calling `add_custom_action`.
|
|
```cpp
|
|
// Add a custom action property. When using this settings type, the "PowertoyModuleIface::call_custom_action()"
|
|
// method should be overridden as well.
|
|
settings.add_custom_action(
|
|
L"test_custom_action", // action name.
|
|
L"This is what a CustomAction property looks like", // label above the field: a string literal or a resource id
|
|
L"Call a custom action", // button text: a string literal or a resource id
|
|
L"Press the button to call a custom action in the Example PowerToy" // display values / extended info: a string literal or a resource id
|
|
);
|
|
```
|
|
|
|
When the custom action button is pressed, the PowerToy's `call_custom_action()` is called with a serialized [`PowerToysSettings::CustomActionObject`](/src/common/settings_object.h) object.
|
|
```cpp
|
|
// Signal from the Settings editor to call a custom action.
|
|
// This can be used to spawn more complex editors.
|
|
virtual void call_custom_action(const wchar_t* action) override {
|
|
static UINT custom_action_num_calls = 0;
|
|
try {
|
|
// Parse the action values, including name.
|
|
PowerToysSettings::CustomActionObject action_object =
|
|
PowerToysSettings::CustomActionObject::from_json_string(action);
|
|
|
|
if (action_object.get_name() == L"test_custom_action") {
|
|
// Custom action code to increase and show a counter.
|
|
++custom_action_num_calls;
|
|
std::wstring msg(L"I have been called ");
|
|
msg += std::to_wstring(custom_action_num_calls);
|
|
msg += L" time(s).";
|
|
MessageBox(NULL, msg.c_str(), L"Custom action call.", MB_OK | MB_TOPMOST);
|
|
}
|
|
}
|
|
catch (std::exception ex) {
|
|
// Improper JSON.
|
|
}
|
|
}
|
|
```
|
|
|
|
### Settings Persistence
|
|
|
|
By default, the PowerToys settings are persisted in the User's `%LocalAppData%\Microsoft\PowerToys` path.
|
|
Each PowerToy has its own folder for saving the persisted settings data.
|
|
|
|
Loading and saving the settings in the default location can be achieved through the use of a [`PowerToysSettings::PowerToyValues`](/src/common/settings_object.h) object.
|
|
|
|
#### Loading settings
|
|
|
|
The PowerToy can load the saved `PowerToyValues` object through the use of the `load_from_settings_file` method.
|
|
|
|
Here's an example:
|
|
```cpp
|
|
// Load the settings file.
|
|
void ExamplePowertoy::init_settings() {
|
|
try {
|
|
// Load and parse the settings file for this PowerToy.
|
|
PowerToysSettings::PowerToyValues settings =
|
|
PowerToysSettings::PowerToyValues::load_from_settings_file(get_name());
|
|
|
|
// Load the bool property.
|
|
if (settings.is_bool_value(L"test_bool_toggle")) {
|
|
g_settings.test_bool_prop = settings.get_bool_value(L"test_bool_toggle");
|
|
}
|
|
|
|
// Load the int property.
|
|
if (settings.is_int_value(L"test_int_spinner")) {
|
|
g_settings.test_int_prop = settings.get_int_value(L"test_int_spinner");
|
|
}
|
|
|
|
// Load the string property.
|
|
if (settings.is_string_value(L"test_string_text")) {
|
|
g_settings.test_string_prop = settings.get_string_value(L"test_string_text");
|
|
}
|
|
|
|
// Load the color property.
|
|
if (settings.is_string_value(L"test_color_picker")) {
|
|
g_settings.test_color_prop = settings.get_string_value(L"test_color_picker");
|
|
}
|
|
}
|
|
catch (std::exception ex) {
|
|
// Error while loading from the settings file. Let default values stay as they are.
|
|
}
|
|
}
|
|
```
|
|
|
|
#### Saving settings
|
|
|
|
The PowerToy can save the `PowerToyValues` object received in `set_config` through the use of the `save_to_settings_file` method.
|
|
|
|
Here's an example:
|
|
```cpp
|
|
// Called by the runner to pass the updated settings values as a serialized JSON.
|
|
virtual void set_config(const wchar_t* config) override {
|
|
try {
|
|
// Parse the input JSON string.
|
|
PowerToysSettings::PowerToyValues values =
|
|
PowerToysSettings::PowerToyValues::from_json_string(config);
|
|
...
|
|
values.save_to_settings_file();
|
|
}
|
|
catch (std::exception ex) {
|
|
// Improper JSON.
|
|
}
|
|
}
|
|
```
|
|
|
|
Alternatively, the `PowerToyValues` object can be built manually and then saved if more complex logic is needed:
|
|
```cpp
|
|
// This method of saving the module settings is only required if you need to do any
|
|
// custom processing of the settings before saving them to disk.
|
|
void ExamplePowertoy::save_settings() {
|
|
try {
|
|
// Create a PowerToyValues object for this PowerToy
|
|
PowerToysSettings::PowerToyValues values(get_name());
|
|
|
|
// Save the bool property.
|
|
values.add_property(
|
|
L"test_bool_toggle", // property name
|
|
g_settings.test_bool_prop // property value
|
|
);
|
|
|
|
// Save the int property.
|
|
values.add_property(
|
|
L"test_int_spinner", // property name
|
|
g_settings.test_int_prop // property value
|
|
);
|
|
|
|
// Save the string property.
|
|
values.add_property(
|
|
L"test_string_text", // property name
|
|
g_settings.test_string_prop // property value
|
|
);
|
|
|
|
// Save the color property.
|
|
values.add_property(
|
|
L"test_color_picker", // property name
|
|
g_settings.test_color_prop // property value
|
|
);
|
|
|
|
// Save the PowerToyValues JSON to the power toy settings file.
|
|
values.save_to_settings_file();
|
|
}
|
|
catch (std::exception ex) {
|
|
// Couldn't save the settings.
|
|
}
|
|
}
|
|
```
|
|
|
|
## Add a new PowerToy to the Installer
|
|
|
|
In the `installer` folder, open the `PowerToysSetup.sln` solution.
|
|
Under the `PowerToysSetup` project, edit `Product.wxs`.
|
|
You will need to add a component for your module DLL. Search for `Module_ShortcutGuide` to see where to add the component declaration and where to reference that declaration so the DLL is added to the installer.
|
|
Each component requires a newly generated GUID (you can use the Visual Studio integrated tool to generate one).
|
|
Repeat the process for each extra file your PowerToy module requires.
|
|
If your PowerToy comes with a subfolder containing for example images, follow the example of the `PowerToysSvgs` component.
|
