However, it is recommended that you use the colour gallery as a more advanced example, and if you are basing your code on anything, then it is probably easier to rip functionality out of a cloned ColourGallery than to add the desired functionality to the ExampleGallery. ********************************************************************************************/ class ExampleGallery : public Gallery { CC_DECLARE_DYNCREATE( ExampleGallery ) public: ExampleGallery(); MsgResult Message(Msg* Message); protected: // Base<->Derived class interface BOOL PreCreate(void); BOOL PostCreate(void); // Initialise display-related stuff before/after the window is created BOOL DoRedrawAnItem(ListItem *Item, BOOL Large, UINT32 DisplayMode); // Redraws the given item appropriately for large/small mode, and // using the given derived class DisplayMode (see DoDisplayMode... below) // returns TRUE if it redrew successfully BOOL PrepareToDelete(void); // returns TRUE if the selection can be deleted, or FALSE if not // May alter the selection as appropriate (after getting user confirmation) BOOL DoDeleteSelection(void); // Force-deletes anything still remaining in the selection // returns TRUE if successful ListItem *DoCreateNewItem(ListItem *BasedOn); // Applies the appropriate action to create a new item, based upon // the 'BasedOn' item or the attribs of the document selection in some way // Returns NULL, or the new item void DoApplyItem(ListItem *ItemToApply); // Applies the appropriate action to apply the given item to the document BOOL DoRedefineItem(ListItem *ItemToRedefine); // Redefines the given item (allow the user to edit it for example) // Returns FALSE if the value of the item definitely has not changed // Returns TRUE if the item has changed, or if it is unknown whether it was changed StringBase *GetItemText(ListItem *TheItem); // Returns NULL, or a pointer to the text to use in the listbox. // This is an early development aid while we're waiting for the advent // of proper user-redraw. void SortModeHasBeenChanged(BOOL SetDerivedSortsToo); // Called when the display dialogue has set a new sort mode, to make the // Gallery (and related entities) redisplay its list in the new order. // Note that the base class method for this MUST be calleded in derivations BOOL DoSetDisplayModes(GalleryDisplayDlg *TheDialogue); // Called to set up the display mode combo box (large icons, full info etc) // This will call TheDialogue->SetDisplayModeName repeatedly to set all // available modes.
