| IMPORT_C void | AddCommandToStackL | ( | TInt | aCommandId, |
| const TDesC * | aText, | |||
| const CFbsBitmap * | aBitmap, | |||
| const CFbsBitmap * | aMask | |||
| ) | ||||
Push a command ID + text + image binding onto the command stack.
Sets the command button to respond to aCommandId. Sets aText as the text in the command button. Sets aBitmap and aMask as the bitmap and mask of the command button. The previous command can be restored on the command button by a subsequent call to PopCommandFromStack() .
| TInt aCommandId | Command ID to be generated by pressing this button |
| const TDesC * aText | Text to display on the button |
| const CFbsBitmap * aBitmap | Bitmap to display on the button |
| const CFbsBitmap * aMask | Mask to use. May be Null |
| IMPORT_C void | ConstructFromResourceL | ( | TResourceReader & | aReader | ) | [virtual] |
| TResourceReader & aReader | Fully constructed resource reader |
| IMPORT_C void * | ExtensionInterface | ( | TUid | aInterface | ) | [private, virtual] |
From CAknControl
| TUid aInterface |
| IMPORT_C void | HandlePointerEventL | ( | const TPointerEvent & | aPointerEvent | ) | [virtual] |
| const TPointerEvent & aPointerEvent | Event to handle |
| IMPORT_C CEikLabel * | Label | ( | ) | const |
Access the label control that implements the text label of the button. Ownership is not transferred.
| IMPORT_C CEikImage * | Picture | ( | ) | const |
Access the CEikImage that implements the picture component of the button. Ownership is not transferred.
| IMPORT_C TInt | PopCommandFromStack | ( | ) |
Remove the top (most recently added) command binding from the command stack
Pops the current command from the stack, if there is one. Restores the command button to respond to the previous commandId before the last push to the stack. The text, bitmap and mask are also restored to the previous values (before the last push was made).
| IMPORT_C TBool | RemoveCommandFromStack | ( | TInt | aCommandId | ) |
Find the stacked command with a given command ID and remove it from the stack
Removes the command which has aCommandId from the stack of commmands.
| TInt aCommandId | ID of the command to be removed |
