Python QPushButton.setMinimumHeight方法代码示例

# 需要导入模块: from python_qt_binding.QtGui import QPushButton [as 别名]
# 或者: from python_qt_binding.QtGui.QPushButton import setMinimumHeight [as 别名]
class ButtonSetPopupSelector(QDialog):
    '''
    An interactive dialog that displays successive sets of
    buttons. When each set is displayed, user may ask for the
    next available set, the previous. already seen set, or the
    user may accept the currently displayed set. A cancel is 
    available as well. 
    
    The call and return protocol is as follows:

      - The caller creates a fresh dialog instance of this class,
        passing an iterator. The iterator's next() method returns 
        an array of ButtonProgram instances each time it is called. (When the
        iterator is exhausted, the user is able to use a 'Previous'
        button to view the previously seen sets again).
      - The caller invokes the exec_() method on the dialog instance.
      - The exec_() method returns:
          
              - -1, if the iterator yielded no button label arrays at all.
              - 0, if the user canceled, and 
              - 1 if the user accepted one of the sets.

      - If the exec_() method returned 1, the caller may obtain an array with the
        ButtonProgram instances of the currently showing (and therefore accepted) buttons.
        The array is obtained from the dialog instance via method getCurrentlyShowingSetLabels(self).
