Returns a value that indicates whether the specified cell is frozen.
#include "ltwrappr.h"
L_BOOL LImageViewerCell::IsCellFrozen(uFlags);
Reserved for future use. Pass 0.
Value | Meaning |
---|---|
TRUE | The cell is frozen. |
FALSE | The cell is not frozen, or an error occurred. To get extended error information, call GetLastError. |
To freeze or un-freeze a cell, call LImageViewerCell::FreezeCell.
When a cell is frozen no actions using the mouse or the keyboard can be performed on the cell. Some cell properties can still be changed manually however, using LImageViewerCell::SetCellProperties, LImageViewerCell::SelectCell and LImageViewer::SetProperties. For more information on actions associated with a container, refer to Applying Actions.
This procedure unfreezes any frozen cell.
