Struct GraphicsCapturePicker

pub struct GraphicsCapturePicker;

Expand description

Helper for prompting the user to pick a window or monitor using the system Graphics Capture Picker.

Implementations§

Source §

impl GraphicsCapturePicker

Source

pub fn pick_item() -> Result<Option<PickedGraphicsCaptureItem>, Error>

Shows the system Graphics Capture Picker dialog and returns the chosen item.

A tiny, off-screen tool window is created as the picker owner and initialized via IInitializeWithWindow. While the picker is visible, a minimal message pump is run to keep the UI responsive.

§Returns

Ok(Some(PickedGraphicsCaptureItem)) if the user selects a target
Ok(None) if the picker completes without a result

§Errors

Error::Canceled when the user cancels the picker
Error::WindowsError for underlying Windows API failures
