    Michael,

    Could you give the group a summary of how QtH fits in with the other
    Qt code, i.e., from a software design perspective?  What I worry
    about is having multiple hunks of Qt code (this for GUI, that for
    QtH, something else for a variable editor) and never really finding
    a nice way of incorporating widgets.



It does not "fit" into the rest of octave/Qt code, it has been developed
independently, when the octave GUI didn't exist yet.

What does it provide?  Is it basically a graphics toolkit?

It's a Qt-based graphics toolkit that uses the OpenGL renderer. It also implements support for the uiXXX functions.

 

 From the name, I had imagined it something to do with HandyDandles.  Is it duplicating some UI objects already present in the GUI?

No.

 

 Does it use the same QApplication as the GUI?

Yes. It hooks into an existing QApplication. It does not provide its own QApplication. It runs in the regular UI thread (unlike FLTK), which makes it more responsive to user interaction.

Michael.
