Buttons - how to create a blinking button

[Mih_Mih]

Hello!
Please tell me how to create a blinking button. I use STM32F7-Discovery

You can either use the flashing property provided by GWIN (gwinSetFlashing()) or you can implement a custom widget that uses a GTIMER internally to render if you need more control.

Do not simply call gwinHide() and gwinShow() periodically. While that has visually the same effect you'll not get what you want as your button will not receive any events while not being visible (meaning you can't click it).

If you look at the widgets demo one of the buttons in the widget demo flashes.

Many thanks, dear friends!

Does not work

My Init and call function:

In "gfxconf.h"

#define GWIN_NEED_FLASHING         TRUE

/********************************************************/
/* GTIMER stuff                                         */
/********************************************************/
#define GFX_USE_GTIMER                                         TRUE

#define GTIMER_THREAD_PRIORITY                         NORMAL_PRIORITY
#define GTIMER_THREAD_WORKAREA_SIZE             2048

in "gui.c"

if (((GEventGWinButton *)pe)->gwin  == ghPushbutton_1) 

{

  gwinFlash(ghPushbutton_1);

}

Button not Blinking.....Do I need to include something else ??
