I need to create a button that let me choose a default color for a grid column in the setup of the application, like the BG choice in the UWord example application. Is possible to make this? I don't find example.. Thanks
Sam

Hi Sam,

There are several widgets to handle colors in U++. They are described in this manual page. Best choice for you would be probably ColorPusher, which can be easily used like this:

#include <CtrlLib/CtrlLib.h>
using namespace Upp;

class win : public TopWindow{
public:
	typedef win CLASSNAME;
	ColorPusher cp;
	Label l;
	void DoSomething(){
		l.SetInk(cp.GetData());
	}
	win(){
		cp.SetRect(10,30,40,20);
		cp.SetData(Black());
		cp<<=THISBACK(DoSomething);
		Add(cp);
		l.SetText("Color test").SetRect(10,10,150,20);
		Add(l);
	}
};

GUI_APP_MAIN{
	win().Run();
}

Of course you would have to change DoSomething to actually do what you need with the selected color. Wink
