get_screen_point int function(cef_render_handler_t* self, cef_browser_t* browser, int viewX, int viewY, int* screenX, int* screenY) nothrow get_screen_point;: Called to retrieve the translation from view DIP coordinates to screen coordinates. Windows/Linux should provide screen device (pixel) coordinates and MacOS should provide screen DIP coordinates. Return true (1) if the requested coordinates were provided.
get_touch_handle_size void function(cef_render_handler_t* self, cef_browser_t* browser, cef_horizontal_alignment_t orientation, cef_size_t* size) nothrow get_touch_handle_size;: Called to retrieve the size of the touch handle for the specified |orientation|.
get_view_rect void function(cef_render_handler_t* self, cef_browser_t* browser, cef_rect_t* rect) nothrow get_view_rect;: Called to retrieve the view rectangle in screen DIP coordinates. This function must always provide a non-NULL rectangle.
on_accelerated_paint void function(cef_render_handler_t* self, cef_browser_t* browser, cef_paint_element_type_t type, size_t dirtyRectsCount, const(cef_rect_t)* dirtyRects, void* shared_handle) nothrow on_accelerated_paint;: Called when an element has been rendered to the shared texture handle. |type| indicates whether the element is the view or the popup widget. |dirtyRects| contains the set of rectangles in pixel coordinates that need to be repainted. |shared_handle| is the handle for a D3D11 Texture2D that can be accessed via ID3D11Device using the OpenSharedResource function. This function is only called when cef_window_tInfo::shared_texture_enabled is set to true (1), and is currently only supported on Windows.
on_ime_composition_range_changed void function(cef_render_handler_t* self, cef_browser_t* browser, const(cef_range_t)* selected_range, size_t character_boundsCount, const(cef_rect_t)* character_bounds) nothrow on_ime_composition_range_changed;: Called when the IME composition range has changed. |selected_range| is the range of characters that have been selected. |character_bounds| is the bounds of each character in view coordinates.
on_paint void function(cef_render_handler_t* self, cef_browser_t* browser, cef_paint_element_type_t type, size_t dirtyRectsCount, const(cef_rect_t)* dirtyRects, const(void)* buffer, int width, int height) nothrow on_paint;: Called when an element should be painted. Pixel values passed to this function are scaled relative to view coordinates based on the value of CefScreenInfo.device_scale_factor returned from GetScreenInfo. |type| indicates whether the element is the view or the popup widget. |buffer| contains the pixel data for the whole image. |dirtyRects| contains the set of rectangles in pixel coordinates that need to be repainted. |buffer| will be |width|*|height|*4 bytes in size and represents a BGRA image with an upper-left origin. This function is only called when
on_popup_show void function(cef_render_handler_t* self, cef_browser_t* browser, int show) nothrow on_popup_show;: Called when the browser wants to show or hide the popup widget. The popup should be shown if |show| is true (1) and hidden if |show| is false (0).
on_popup_size void function(cef_render_handler_t* self, cef_browser_t* browser, const(cef_rect_t)* rect) nothrow on_popup_size;: Called when the browser wants to move or resize the popup widget. |rect| contains the new location and size in view coordinates.
on_scroll_offset_changed void function(cef_render_handler_t* self, cef_browser_t* browser, double x, double y) nothrow on_scroll_offset_changed;: Called when the scroll offset has changed.
on_text_selection_changed void function(cef_render_handler_t* self, cef_browser_t* browser, const(cef_string_t)* selected_text, const(cef_range_t)* selected_range) nothrow on_text_selection_changed;: Called when text selection has changed for the specified |browser|. |selected_text| is the currently selected text and |selected_range| is the character range.
on_touch_handle_state_changed void function(cef_render_handler_t* self, cef_browser_t* browser, const(cef_touch_handle_state_t)* state) nothrow on_touch_handle_state_changed;: Called when touch handle state is updated. The client is responsible for rendering the touch handles.
on_virtual_keyboard_requested void function(cef_render_handler_t* self, cef_browser_t* browser, cef_text_input_mode_t input_mode) nothrow on_virtual_keyboard_requested;: Called when an on-screen keyboard should be shown or hidden for the specified |browser|. |input_mode| specifies what kind of keyboard should be opened. If |input_mode| is CEF_TEXT_INPUT_MODE_NONE, any existing keyboard for this browser should be hidden.
start_dragging int function(cef_render_handler_t* self, cef_browser_t* browser, cef_drag_data_t* drag_data, cef_drag_operations_mask_t allowed_ops, int x, int y) nothrow start_dragging;: Called when the user starts dragging content in the web view. Contextual information about the dragged content is supplied by |drag_data|. (|x|, |y|) is the drag start location in screen coordinates. OS APIs that run a system message loop may be used within the StartDragging call.
update_drag_cursor void function(cef_render_handler_t* self, cef_browser_t* browser, cef_drag_operations_mask_t operation) nothrow update_drag_cursor;: Called when the web view wants to update the mouse cursor during a drag & drop operation. |operation| describes the allowed operation (none, move, copy, link).
