This instance method forces a palette object to repaint the specified cell area.
Syntax
_wpRedrawCell(somSelf, pCell)
Parameters
- somSelf (WPPalette *) - input
- Pointer to the object on which the method is being invoked.
- Points to an object of class WPPalette.
- pCell (PCELL) - input
- Pointer to the cell within the palette that needs repainting.
Returns
- rc (BOOL) - returns
- Success indicator.
- TRUE The method call was successful.
- FALSE The method call was unsuccessful.
How to Override
Overriding this method is not recommended.
Usage
This method may be called at any time to force the palette object to repaint the specified cell in all of its currently open views.
Remarks
This method is used as cell values within the palette are altered. For example, when the color selector dialog is changing the color of a palette cell in the color palette, this method is invoked to refresh the color back in the open views of the color palette object.
Example Code
#define INCL_WINWORKPLACE #include <os2.h> WPPalette *somSelf; /* Pointer to the object on which the method is being invoked. */ PCELL *pCell; /* Pointer to the cell within the palette that needs repainting. */ BOOL rc; /* Success indicator. */ rc = _wpRedrawCell(somSelf, pCell);
