Function Documentation

_compose_always_on_top_dirty()

void _compose_always_on_top_dirty ( ChCanvas *  canvas, WinSharedInfo *  info, bool  _window_moving_, Window *  focusedWin, Window *  win  )

extern

_compose_always_on_top_dirty – compose always on top window's dirty rectangles

Parameters

canvas	– Pointer to canvas
info	– Pointer to window's shared info
_window_moving_	– window moving bit
focusedWin	– Pointer to focused Window
win	– Pointer to main window

_compose_always_on_top_entire()

void _compose_always_on_top_entire ( ChCanvas *  canvas, Window *  win, bool  _always_on_top_update, bool  _window_moving_, WinSharedInfo *  info, Window *  rootWin  )

extern

_compose_always_on_top_entire – compose entire always on top window

_compose_dirty_area_()

void _compose_dirty_area_ ( ChCanvas *  canvas, Window *  win, Window *  focusedWin, WinSharedInfo *  info  )

extern

Check for small area updates !! not entire window.

_compose_entire_window()

void _compose_entire_window ( ChCanvas *  canvas, Window *  win, bool  _window_update_all_, WinSharedInfo *  info, Window *  focusedWin, bool  _window_moving_, bool  _shadow_update  )

extern

compose_entire_window – composes an entire window to canvas

Parameters

canvas	– Pointer to Deodhai canvas
win	– Pointer to main window to compose
_window_update_all_	– update all bit
info	– Pointer to main window info struct
focusedWin	– focused window pointer
_window_moving_	– window moving bit
_shadow_update	– shadow update bit which tells if we need to update shadows or not

if ((info->x - SHADOW_SIZE) <= 0) { info->x = 5 + SHADOW_SIZE; winx = info->x; glass_invalidate(win); }

if ((info->y - SHADOW_SIZE) <= 0) { info->y = 5 + SHADOW_SIZE; winy = info->y; glass_invalidate(win); }

if ((info->x + 24) >= (int)canvas->screenWidth) info->x = canvas->screenWidth - 24;

if ((info->y + 24) >= (int)canvas->screenHeight) info->y = canvas->screenHeight - 24;

compose_window_scaled_to()
