# Custom HotKey Control
|
|
|
|
The Settings project provides a custom hotkey control which consumes key presses. This control can be used to set the hotkey of any PowerToy.

|
|
|
#### [`HotkeySettingsControlHook.cs`](/src/settings-ui/Settings.UI.Library/HotkeySettingsControlHook.cs)
|
|
|
|
- This function initializes and starts the [`keyboardHook`](src/common/interop/KeyboardHook.cpp) for the hotkey control.
|
|
|
|
```csharp
|
|
public HotkeySettingsControlHook(KeyEvent keyDown, KeyEvent keyUp, IsActive isActive, FilterAccessibleKeyboardEvents filterAccessibleKeyboardEvents)
|
|
{
|
|
_keyDown = keyDown;
|
|
_keyUp = keyUp;
|
|
_isActive = isActive;
|
|
_filterKeyboardEvent = filterAccessibleKeyboardEvents;
|
|
_hook = new KeyboardHook(HotkeySettingsHookCallback, IsActive, FilterKeyboardEvents);
|
|
_hook.Start();
|
|
}
|
|
|
|
```
|
|
|
|
#### [`HotkeySettingsControl.xaml.cs`](/src/settings-ui/Settings.UI/HotkeySettingsControl.xaml.cs)
|
|
|
|
- The function of this class is to update the state of the keys being pressed within the custom control. This information is stored in `internalSettings`.
|
|
|
|
- It provides the following callbacks to the `HotKeySettingsControlHook`:
|
|
|
|
- `KeyUp`: Resets the key state in `internalSettings` when a key is released.
|
|
- `KeyDown`: Updates the user facing text of the hotkey control as soon as a key is pressed.
|
|
- `isActive`: Sets the current status of the keyboard hook.
|
|
- `FilterAccessibleKeyboardEvents`: This function is used to ignore the `Tab` and `Shift+Tab` key presses to meet the accessibility requirements.
|
|
|
|
#### [`HotkeySettings.cs`](/src/settings-ui/Settings.UI.Library/HotkeySettings.cs)
|
|
|
|
- Contains the structure of a HotKey where it is represented as a combination of one of the modifier keys (`Alt`, `Shift`, `Win` and `Ctrl`) and a non-modifier key.
|
|
|
|
#### Note
|
|
- The control displays all key presses to the user (except Tab and Shift+Tab which move focus out of the control). However, when the focus is being lost from the control, the `lastValidHotkeySettings` is set as the user facing text.
