WinUI3 : How to reference existing WinUI3 element programatically
Im working on the WinUI3 desktop app in C++ programatically without using any XAML files. From creation of the App to the creation of a button is done programmatically without any XAML files.
Now suppose I have 2 Canvas in Window (Say canvas 1 and Canvas 2) and Each canvas has 1 button. Now I have to change the color of canvas 2 when the canvas 1 button is clicked. When I get the button click event from Canvas 1's button, how can I access the Canvas 2 object?
Possible solutions I came across
- Set an ID as the name for Canvas 2 and get the Canvas 2 reference from traversing the Visual tree
- Store the Canvas 2 object somewhere and access it when the button is clicked.
Are these 2 the only valid option or does Microsoft provide any artifact to achieve this?
My issue with the above possible solutions is,
- Solution 1: High-time complexity
- Solution 2: If I want to store a WinUI3 control, I only want to store it as void pointer which can't be achieved.
