The default feature of the window manager is to send a wm_paint to each window to be repainted. This will lead to the flicker effect. To suppress the flickering effect of these 66 windows, storage devices can be automatically used for repainting operations. The method is to set wm_cf_memdev and 67 in the create window. Use the wm_setcreateflags () function to set the default create tag, or use the wm_enablememdev () function (). WM then 68 redirects the wm_paint message output to the storage device and then copies it to the display. If the memory of the entire window is insufficient, the segment is automatically used for 69. The storage device is only for temporary use and will be removed after the painting operation is complete. 70 */71 wm_setcreateflags (wm_cf_memdev); // It is used as the default marker 72 wm_enablememdev (wm_hbkwin) when a new window is created ); // enable the use of storage devices to redraw the window 73 wm_setcallback (wm_hbkwin, & _ cbbkwindow); // set the callback routine of the window, call the wm_paint message to initialize the background 74 // create a non-blocking dialog box 75 hwin = gui_createdialogbox (_ adialogorder, gui_countof (_ adialogorder), & _ cbdialogorder, wm_hbkwin, 0, 0 ); 76 while (1) {77 If (!
