Hi Sergey,

 

Sorry for the late reply.

1. You can check for mouse position in update() and check if mouse button 2 is pressed:
   
   

   int mouse_x = gui.getMouseX() - widget.getPositionX();
   int mouse_y = gui.getMouseY() - widget.getPositionY();
   	
   if(mouse_x > 0 && mouse_x < widget.getWidth() && mouse_y > 0 && mouse_y < widget.getHeight()) {
   	if(engine.app.clearMouseButtonState(APP_BUTTON_RIGHT) == true) {
   			right_clicked_callback();
   	}
   }

2. You can create new parameter <data> inside the *.ui-files. After that you can get acces to it via getData() function. For example:
   
   

   <?xml version="1.0" encoding="utf-8"?>
   <ui version="1.00">
   	<icon name="my_icon" export="1">
   		<tooltip>my icon</tooltip>
   		<callback type="clicked">icon_clicked</callback>
   		<data>my data</data>
   	</icon>
   </ui>
   

3. I'm afraid there is no way to control segments count, sorry.

Hi Sergey,

 

Yes, you can calculate current highlighted item based on current mouse position and item height. Here is a basic example, where calculation based only on item's font size:

int step = widget.getFontSize();
   int item = mouse_y / step;
   forloop(int i = 0; widget.getNumItems()) {
    if(i == item) {
     widget.setCurrentItem(widget.getItem(item));
     break;
    }
   }

If you are using texture for your items you will need to get it's height instead of font size.

 

Thanks!
