Hi Tony!

 

Have you looked at samples/widgets/sprite_03 sample?

Hi Andrey,

 

I will go to look :)

 

Thanks

[unclebob]

You're welcome. :)

 

I'll wait for your feedback before I resolve this topic.

Unfortunately, Andrey doesn't work for us, The sample show the drag and drop between Widget.

We want drag and drop between Widget and "viewport" (without gui). Looking other sample we will try with the other event ENTER and LEAVE, may be that can work.

Hi Tony,

 

Did you get any results on drag'n'drop feature?

Hi Andrey,

 

Unfortunately, it's no so easy to add it inside our code, because we need to change a lot of code adding many callback .... for quick result we choose other option, we have a list of our Widget and when we receive the release of the mouse, we check for each widget the position of the mouse and the position of the widget. It's not the better way to do it, but could be work quickly.

We use these functions

/*
 */
int mouse_is_over_unigine_widget(Widget w) {
	if(w.isHidden()) return 0;
	int mx= w.getMouseX();
	int my= w.getMouseY();
	return ((mx > 0) && (my > 0) && (mx < w.getWidth()) && (my < w.getHeight()));
}

/*
 */
int mouse_is_over_any_unigine_widget() {
	forloop(int i=0;engine.gui.getNumChilds()) {
		if(mouse_is_over_unigine_widget(engine.gui.getChild(i)))
			return 1;
	}
	return 0;
}

Hi,

I thought id do an update for v2.12.01 C# component system, because it is not one on one conversion.

	public WidgetButton button;

	button = new WidgetButton("button text");
	Gui gui = Gui.Get();
	gui.AddChild(button,Gui.ALIGN_LEFT);

	public static bool mouse_is_over_unigine_widget(Widget w)
	{
		if (w.Hidden) return false;
		bool r = (
			(w.MouseX > 0 ) &&
			(w.MouseY > 0 ) &&
			(w.MouseX < w.Width) &&
			(w.MouseY < w.Height) );
		return r;
	}

	public static bool mouse_is_over_any_unigine_widget()
	{
		for (int i = 0; i < Gui.Get().NumChildren; i++)
		{
			if(mouse_is_over_unigine_widget(Gui.Get().GetChild(i))) 
				return true;
		}
		return false;
	}
