Functions

void lv_windows_platform_init(void)

Initialize the LVGL Windows backend.

Remark

This is a private API which is used for LVGL Windows backend implementation. LVGL users shouldn't use that because the LVGL has already used it in lv_init.

lv_windows_window_context_t *lv_windows_get_window_context(HWND window_handle)

Get the window context from specific LVGL display window.

Remark

This is a private API which is used for LVGL Windows backend implementation. LVGL users shouldn't use that because the maintainer doesn't promise the application binary interface compatibility for this API.

Parameters:

window_handle -- The window handle of specific LVGL display window.

Returns:

The window context from specific LVGL display window.
