EVENT_PANEL_MOVING

Description

As a user or program moves a panel, LabWindows/CVI generates an EVENT_PANEL_MOVING event and sends the event to the callback function associated with the panel.

This event is not swallowable; however, you can use eventData2 to restrict the size or position of the panel.

Note  Consider the following caveats when using this event: For all panels on Windows and for child panels on Linux, the EVENT_PANEL_MOVE event is generated after the user or program has moved the panel, and the EVENT_PANEL_MOVING event is generated as the user or progam moves the panel. (Linux) For parent panels, LabWindows/CVI continuously generates EVENT_PANEL_MOVE events instead of EVENT_PANEL_MOVING events as the user or program moves the panel. LabWindows/CVI does not generate EVENT_PANEL_MOVING events for parent panels. The GetPanelEventRect function returns the panel bounds that includes the titlebar and frame. GetPanelAttribute and SetPanelAttribute with ATTR_TOP, ATTR_LEFT, ATTR_HEIGHT, and ATTR_WIDTH refer to the panel bounds not including the titlebar and frame. Use the panel attributes ATTR_TITLEBAR_ACTUAL_THICKNESS, ATTR_FRAME_ACTUAL_WIDTH, and ATTR_FRAME_ACTUAL_HEIGHT to go from one bounding rectangle to the other.
