The Qt documentation in C++ of this class can be read here: http://doc.trolltech.com/4.3/qpushbutton.html
A control for the form object, provides a push button.
The command button, or push button, is perhaps the most commonly used control in any graphical user interface. Push (click) a button to command the computer to perform some action, or to answer a question. Typical buttons are OK, Apply, Cancel, Close, Yes, No and Help.
A command button is rectangular and typically displays a text label describing its action. An underlined character in the label (signified by preceding it with an ampersand in the text) indicates an accelerator key. Command buttons can display a textual label or an icon.
Please read the control class overview Control as well.
Property AutoDefault As Boolean (ReadWrite)
Property Default As Boolean (ReadWrite)
This property holds whether the CommandButton is the default button.
If it is to true then the CommandButton will be pressed if the user presses the Enter (or Return) key in a dialog.
Regardless of focus, if the user presses Enter: If there is a default button the default button is pressed; otherwise, if there are one or more autoDefault buttons.
The default button behavior is provided only in dialogs. Buttons can always be clicked from the keyboard by pressing Spacebar when the button has focus.
Property Checkable As Boolean (ReadWrite)
If it is true, the CommandButton appears as checkable button. If you would like to group several buttons as auto-exclusive group, set for all buttons the same group name.
Property Checked As Boolean (ReadWrite)
If it is true, the CommandButton is checked.
Property Flat As Boolean (ReadWrite)
If it is true, the CommandButton appears as flat button. This is only useful to change the visual appearance.
Property Icon As String (ReadWrite)
Either an icon or caption is visible on a CommandButton. If you set an icon, the caption will not be displayed. An icon can be an absolute path to an image file (png, jpg,…) like c:\myfolder\myimage.png or can be an relative path to the current project like myimage.png (which is present in the current project directory). Relative paths are recommended.
Might be a String containing binary data. See the binary project example for using.
Dim c As CommandButton c = Control("Button1") ' Button1 is declared as CommandButton in this form c.Icon= "tux.jpg" ' relative path. File exists in current project directory
