I am trying to use STemWin 532 on a STM32f467 board. I created a framewin with 4 buttons using GuiBuilder and ran the application, but the display is scrambled. This is how a framewin with 4 buttons looks like on my display :

.

I've also attached my 'main.c' and framewin source files. I tried adding an osDelay after GUI_Exec() but it did not work.

Any help is greatly appreciated.

Hello!

When you make a custom dialog,  you must make also a function to paint the dialog

Inside your message callback function you must catch the case 'case WM_PAINT:'

When the GUI  needs to paint the dialog(because is invalid by some movement ) gives this message to your dialog message map!!
