Specific Issues

  • From Curtis Lisle

idea #1 - I have had trouble initializing widgets to specific values in advance of user input. For example, I've created interfaces with sliders and buttons but I have had trouble getting the widgets to initialize in a state different then the default state. For example, setting a slider to value=26 in the middle of its range without dragging the mouse. The API looks like it is there, but I couldn't get it to work for me. I'm sure I tried setting the state before and after creation, if I remember, but no luck. It may be that I'm not updating the GUI successfully after changing values.

idea #2 - discuss when UI elements need to have Modified() / Update() invoked to refresh their appearance. I used a histogram widget on a project and had to experiment a lot calling the panel and RenderWidowWidget, etc. before I finally got the histogram to update when the input changed.
