-----------------------------------------------------------------------
|
||||
|
||||
Breaking Changes:
|
||||
- Examples: Vulkan: Added extra parameter to ImGui_ImplVulkan_RenderDrawData(). Engine/app is
|
||||
in charge of owning/storing 1 ImGui_ImplVulkan_FrameRenderBuffers per in-flight rendering frame.
|
||||
(The demo helper ImGui_ImplVulkanH_Window structure carries them.) (#2461, #2348, #2378, #2097)
|
||||
- Examples: Vulkan: Added MinImageCount field in ImGui_ImplVulkan_InitInfo, required during
|
||||
initialization to specify the number of in-flight image requested by swap chains.
|
||||
(was previously a hard #define IMGUI_VK_QUEUED_FRAMES 2). (#2071, #1677) [@nathanvoglsam]
|
||||
- Examples: Vulkan: Tidying up the demo/internals helpers (most engine/app should not rely
|
||||
on them but it is possible you have!).
|
||||
|
||||
|
||||
Other Changes:
|
||||
- InputText: Fixed selection background starts rendering one frame after the cursor movement

|
||||
// 2019-XX-XX: *BREAKING CHANGE*: Vulkan: Added MinImageCount field in ImGui_ImplVulkan_InitInfo, required for initialization (was previously a hard #define IMGUI_VK_QUEUED_FRAMES 2). Added ImGui_ImplVulkan_SetSwapChainMinImageCount().
|
||||
// 2019-XX-XX: Vulkan: Added VkInstance argument to ImGui_ImplVulkanH_CreateWindow() optional helper.
|
||||
// 2019-04-04: Vulkan: Avoid passing negative coordinates to vkCmdSetScissor, which debug validation layers do not like.
|
||||
// 2019-04-01: Vulkan: Support for 32-bit index buffer (#define ImDrawIdx unsigned int).
|
