I know the window can be Sizeable() and Zoomable().

But how do you resize the widgets when the window gets resized?

Thanks

Hello Lectus

U++ does it very simple:

- In the Layout Designer

index.php?t=getfile&id=3524&private=0

See the red thick lines and "spring" lines:
-- The thick lines means that that side of the control is attached to that side of the main frame
-- The "spring means that that side of the control is not attached.

Just open a example and play with it. It is very easy and useful.

- In the code
If you want to do it "the hard way" in the code, is very easy too as layout are translated into code with functions like LeftPosZ and so.

Anyway you can go to the GUI Tutorial section 16. Layouts where you can see examples and explanations.

There are more advanced features if you want fancier resizing but I think for now this enough Smile

Thank you for your post! I now understand it!

U++ never fails to amaze me. It was actually pretty simple.
I just set Sizeable().Zoomable() and adjust the springs at the layout editor.
I just needed some explanation like yours to know where to look at. Smile

Hi Lectus,

You can also use the virtual method Layout() in TopWindow object.

Header file

class MyWin : public WithMyWinLayout<TopWindow> {
typedef MyWin CLASSNAME;

public:
MyWin();

private:
virtual void Layout();
};

cpp file

void MyWin::Layout()
{
Size sz = GetSize();

if(sz.cx== something)dosomething with SetRect(p1,p2,p3,p4)or the embedded widgets using layout functions (SizePos() etc..);

TopWindow::Layout(); //call the ancestor method
}

Hope this could be helpful

Regards
