Creating a button dynamically (C++)
Posted: 24 Aug 2014, 04:18
Hi. Sorry if this is a noob question:
I'm trying to create a button dynamically and add it to a loaded XAML via this code:
.h
.cpp
.XAML
(Of course, I just cut an pasted the relevant bits of code above)
Everything about creating the button, adding it to the "SOMEcanvas" sub-canvas and having it display works fine. However, when you mouse over it or click it it does nothing. It acts like a static object rather than a button. Buttons that were created in the XAML work fine.
My assumption is that I'm simply overlooking something? Any help would be appreciated. Thanks...
NOTE 1: The reason for the sub-canvas is that the UI in question will have multiple pages, which is very easy to manage simply by hiding or showing the appropriate sub-canvas, obviously.
NOTE 2: I AM updating the location of this button every few frames using SetRenderTransform() as its location in the display is based off the location of a 3D element in the game world. Not sure if that matters or not, but thought I should mention it regardless.
Finally, as a side question, is there a way to make an image click-able? I mean, I can add an image to a button's content and it works fine. I was just wondering if there was a more efficient means... Thanks again...
