Hello!
My program adds widgets (QPushButtons) like this:
Qt Code: 
  1. Layout->addWidget(MyWidget);
To copy to clipboard, switch view to plain text mode 
and removes them like this:
Qt Code: 
  1. Layout->removeWidget(MyWidget);
To copy to clipboard, switch view to plain text mode 
several times during the code execution.

Although this simple approach works most of the time, sometimes I get weird results. Sometimes after removing my QPushButton, it no loger functions but it is still there and sitting on top of another widget that is supposed to replace it.
Questions:
1. Do you have to check for the presence of a widget before you attempt to remove it? How do you do it?
2. Does something need to be specifically refreshed or redrawn after the widget has been removed?
Thank you!
