Public Member Functions

 GridTab ()
 ~GridTab ()
 GridTab destructor.
virtual BOOL Init ()
 GridTab initialisation routine.
virtual BOOL HandleMsg (DialogMsg *Msg)
 Handles all the Page options tabs messages.
virtual BOOL InitSection ()
 Sets initial values for the Page section of the options dialog box. This section includes the:-.
virtual BOOL CommitSection ()
 Reads the gadgets on the Grid and Ruler Options Tab and sets the appropriate values in the grid in the spread dictated by the OptionsTab class, currently kept up to date with the first spread in the selected document.
virtual BOOL NewUnitsInSection ()
 Function called when new default units come into operation. We must convert all units fields to display in the newly specified units.
virtual BOOL GreySection ()
 Called when the user has closed all documents.
virtual BOOL UngreySection ()
 Called when the user has selected a new document.
BOOL ChangeControlStatus (const BOOL Status)
 Called to grey/ungrey all controls on this tab.
virtual BOOL UpdateSection (String_256 *DocumentName)
 Called when we have switched to a new document and need to update all the controls on this tab. Should only init the tab if the page is present. The document name allows the info field on the tab to be filled in correctly.
BOOL UpdateGridSection ()
 Called when we have undone a default grid resize operation and hence need to update the default grid's details on the page section of this tab. Should only init the tab if the page is present.
virtual CDlgResID GetPageID ()
 Allows the options dialog code to determine the dialog ID of this section.
virtual BOOL IsDocumentOption ()
 Allows the document options dialog code to determine if this tab belongs to the group of document options.
virtual BOOL IsProgramOption ()
 Allows the program options dialog code to determine if this tab belongs to the group of program options.
BOOL InvokeResize (GridResizeInfo *Param)
 Sets the new details of the page size and of the default grid. The default grid should always be resident in the spread. Assumes the class variables pDocument, pSpread have been set up. This function should be used instead of SetNewSizeOfPage and SetDefaultPageGrid as it is undoable and they aren't.

Protected Member Functions

BOOL InitGridSection ()
 Reflects the state of the default grid in the grid tab of the options dialog.

BOOL GridTab::CommitSection (   )  [virtual]
 

Reads the gadgets on the Grid and Ruler Options Tab and sets the appropriate values in the grid in the spread dictated by the OptionsTab class, currently kept up to date with the first spread in the selected document.

Author:
Ed_Cornes (Xara Group Ltd) <camelotdev@xara.com>
Date:
18/10/95
Returns:
TRUE if worked, FALSE if fails
If False is returned then **MUST** have reported error to the user otherwise the dialog box will refuse to close and the user will not know why. Also, individual controls must report their individual errors and not go through some crazy system and then ***NOT*** report the errors
