When creating a canvas widget, if setSize is called after the canvas is added to it's parent the canvas will not display.

This version works

Code Select Expand


tgui::Canvas::Ptr canvas = tgui::Canvas::create();
canvas->setPosition(50,50);
canvas->setSize(100,100);
gui.add(canvas);
canvas->clear("100,100,100");
canvas->display();


When we switch the order of canvas->setSize and gui.add, the canvas no longer displays.

Code Select Expand


tgui::Canvas::Ptr canvas = tgui::Canvas::create();
canvas->setPosition(50,50);
gui.add(canvas);                   // moved before setSize
canvas->setSize(100,100);
canvas->clear("100,100,100");
canvas->display();


It doesn't matter if the parent is gui or another widget (such as panel)
I haven't observed this behavior with any other widgets.

TGUI 0.8.1

Hi Everybody
I'm having problems with the slider widget. I can add it and it shows up just fine, but I can't actually use it in any way, it doesn't move when I click it.

I have tried setting the min, max, step, and value.

Using 0.8, 32bit, Visual Studio 2017

Thanks

Hi everybody.
I have a canvas that the user can click. When they do, I need to find where on the canvas they clicked.
I understand that the "MousePressed" signal comes with a SignalVector2f that gives the mouse position relative to the widget, but I can't find any documentation on how to access or use that data.
Does anybody have any hints?

Thanks
