It is told in AppWizard manual that Image widget supports animated GIF-s: UM03003.pdf:
"6.2.19 JPEG/GIF/BMP
Description
This property allows to add a JPEG, a GIF or a BMP image to an Image object. AnimatedGIFs are supported as well. "

However when animated GIF imported in project Images and the project gets Exported, the animated GIF-s *.c file takes as much as other images (generated from *.png) of the same dimensions (so - contains no more than 1 frame).

I use variable to display the GIF in the Image widget, which works just fine with *.png files, but using the same mechanism (SETBITMAP job and as receiver Image widget) has no effect at all.

How to properly use animated GIF-s in AppWizard? Is there any example or tutorial? Could not find any.

My objective is to show 6 icons changing depending on status and one of them should be animated.

I want to change the color from emWin in runtime for Box object created in AppWizard. How to do that?

If I create in C code progress like this:

void cbID_SCREEN_Initial(WM_MESSAGE * pMsg) {
  GUI_USE_PARA(pMsg);


  PROGBAR_Handle ahProgBar;


  switch (pMsg->MsgId)
  {
    case WM_INIT_DIALOG:
      ahProgBar = PROGBAR_CreateEx (245, 70, 200, 30, pMsg->hWin, WM_CF_SHOW, PROGBAR_CF_HORIZONTAL, GUI_ID_PROGBAR0);
    break;
  }
}

Then I can this code works:

PROGBAR_Handle ahProgBar = WM_GetDialogItem (ID_SCREEN_Initial, GUI_ID_PROGBAR0);
PROGBAR_SetValue (ahProgBar, 12);

However, if I create PROGBAR in AppWizard GUI tool, following lines

PROGBAR_Handle ahProgBar = WM_GetDialogItem (ID_SCREEN_Initial, ID_PROGBAR_Initial);
PROGBAR_SetValue (ahProgBar, 12); <--- crash

give crash in simulator (didn't tried on real hw):
"PROGBAR.c
Wrong handle type or Object not init'ed in PROGBAR_LockH()"

Obviously AppWizard PROGBAR widget isn't the same as emWin widget.

How to properly access AppWizard PROGBAR from C code?
