CPane::IsChangeState

As the pane is being moved, this method analyzes its position relative to other panes, dock rows, and mini-frame windows, and returns the appropriate AFX_CS_STATUS value.

virtual AFX_CS_STATUS IsChangeState(
   int nOffset,
   CBasePane** ppTargetBar
) const;

Parameters

  • [in] nOffset
    Specifies docking sensitivity. For example, a pane that is moved within nOffset pixels from a dock row will be docked.

  • [in] ppTargetBar
    When the method returns, ppTargetBar contains either a pointer to the object to which the current pane should be docked, or NULL if no docking should occur.

Return Value

One of the following AFX_CS_STATUS values:

Description

CS_NOTHING

CS_DELAY_DOCK

The pane is over a dock site that is either another docking pane or an edge of the main frame. The framework docks the pane when the user releases the move.

CS_DELAY_DOCK_TO_TAB

The pane is over a dock site that causes the pane to be docked in a tabbed window. This occurs when the pane is either over the caption of another docking pane or over the tab area of a tabbed pane. The framework docks the pane when the user releases the move.
