Yes, a dialog can have any set of controls. For instance, when you run
Word or Notepad, if they where implemented using IUP, that main interface
is a IupDialog, it contains lots of buttons an the text editor area. When
you want to configure a Paragraph with more parameters that are available o
the main interface, it appears another windows, that also would be an
IupDialog. Inside the dialog will be buttons, labels, text boxes and in
some cases plots of data. A IupPlot is a control just like IupButton is.
The TransparencyIndex attribute is optional. If that line fails, then it
seems the image parameter may not be an imImage as expected. Can tell
what's going on just by the code you sent.
