Radiobutton custom draw problem

[Dvor_nik]

Hi! It seems that there are some problems with the Custom Draw Routines assignment for the RadioButton. Look at the code and comments pls:

	// Custom Draw Routines for RadioButton: replace RadioButton with two (in one) image:
	void gwinRadioDraw_Image(GWidgetObject *gw, void *param) {
		
		coord_t				sy;
		
	    if ((gw->g.flags & GRADIO_FLG_PRESSED)) {
			sy = gw->g.height;
		} else {
			sy = 0;
		}

		gdispGImageDraw(gw->g.display, (gdispImage *)param, gw->g.x, gw->g.y, gw->g.width, gw->g.height, 0, sy);
	}

	// create button widget: ghButton4  - THIS ONE DISPLAYED IMAGES AND WORK GREATE 
	wi.g.show = TRUE;
	wi.g.x = 0;
	wi.g.y = 204;
	wi.g.width = 68;
	wi.g.height = 68;
	wi.g.parent = ghContainerPage0;
	wi.text = "Button";
	wi.customDraw = gwinButtonDraw_Image;
	wi.customParam = &MyImage;          // image, everything OK with button!
	wi.customStyle = 0;
	ghButton4 = gwinButtonCreate(0, &wi);
	gwinSetFont(ghButton4, dejavu_sans_10);
	gwinRedraw(ghButton4);

	
	// create radio button widget: ghRadioButton1 - THIS ONE DISPLAYED STANDART RADIO AND WORK GREATE TOO
	wi.g.show = TRUE;
	wi.g.x = 80;
	wi.g.y = 60;
	wi.g.width = 68;
	wi.g.height = 68;
	wi.g.parent = ghContainerPage0;
	wi.text = "RadioButton1";
	wi.customDraw = gwinRadioDraw_Radio;
	wi.customParam = 0; 
	wi.customStyle = 0;
	ghRadioButton1 = gwinRadioCreate(0, &wi, MAIN_GROUP);
	gwinRadioPress(ghRadioButton1);
	gwinRedraw(ghRadioButton1);


	// create radio button widget: ghRadioButton2 - THIS ONE DOESN'T DISPLAYED and then the microcontroller freezes
	wi.g.show = TRUE;
	wi.g.x = 80;
	wi.g.y = 0;
	wi.g.width = 68;
	wi.g.height = 68;
	wi.g.parent = ghContainerPage0;
	wi.text = "RadioButton2";
	wi.customDraw = gwinRadioDraw_Image;
	wi.customParam = &MyImage;                // the same image!
	wi.customStyle = 0;
	ghRadioButton2 = gwinRadioCreate(0, &wi, MAIN_GROUP);
	gwinRedraw(ghRadioButton2);
}

I tried simple draw image without conditions or simple draw rect or text  instead image, but I always got the same effect. 

uGFX from repository. Everything else works fine.  Could your tell me pls, what's I doing wrong?

Your custom rendering routine seems fine. That definitely shouldn't be a problem. I can't find any problem in the rest of your code either. Can you please use your debugger to grab a stack trace to figure out what causes the crash? Also, check whether it really is a crash. a "freeze" could also just being stuck in a loop waiting for something. Again, using the debugger will give you more information.
