Detailed Description

Application Framework text document view.

Library: ilvappframe

The IlvDvTreeView is a subclass of IlvTreeGadget that implements the IlvDvDocViewInterface interface. It is used for displaying the text of the document in an IlvTreeGadget gadget.
Classes that inherit from the IlvDvTreeView class must be declared and implemented with specific macros, which allows instances of these classes to be created automatically by the document templates.
The following code sample shows how to derive from IlvDvTreeView:

class MyTreeView
: public IlvDvTreeView {
    IlvDvDeclareGadgetViewCreate();
 public:
     MyTreeView(IlvDisplay* display) : IlvDvTreeView(display) {}
     virtual void initializeView();
     ...
 };
 
 // Implementation file
 void
 MyTreeView::initializeView()
 {
     IlvDvTreeView::initializeView();
     // My initialization code here
 }
 ...
 IlvDvPreRegisterGadgetViewClass(MyTreeView, IlvDvTreeView);
 IL_BEGINMODULEINITDEF(mymodule)
     IlvDvPostRegisterDocIlvViewClass(MyTreeView, IlvDvTreeView);
 IL_ENDMODULEINITDEF(mymodule)

Constructor & Destructor Documentation

IlvDvTreeView()

IlvDvTreeView::IlvDvTreeView

(

IlvDisplay *

display

)

Constructs an IlvDvTreeView object.

This constructor creates an instance of IlvDvTreeView whose display is given by the parameter display.

Member Function Documentation

getGraphic()

virtual IlvGraphic* IlvDvTreeView::getGraphic ( )

virtual

Gets the graphic object of the document view.

Must be redefined by the class that implements the interface if the class inherits from the IlvGraphic class. In this case, the redefined method only returns this object. For example, the IlvDvTextView class redefines this method to return (IlvText*)this object. By default, the method returns 0.

Returns

The graphic object of the document view.

Reimplemented from IlvDvDocViewInterface.

getPopupMenuForItem()

virtual IlvPopupMenu* IlvDvTreeView::getPopupMenuForItem ( const IlvTreeGadgetItem *  item )

protectedvirtual

Returns the popup menu shown when a right-click occurs on the item item.

It is called by the method rightClickOnItem.

Parameters

item	The item under the right-click.

getPopupMenuResourceId()

virtual const IlSymbol* IlvDvTreeView::getPopupMenuResourceId ( const IlvTreeGadgetItem *  item ) const

protectedvirtual

Returns the popup menu resource id that will allow you to construct the popup menu shown when a right-click occurs on the item item.

The resource id is the name entered for the corresponding popup menu in the application editor.
It is called by the method getPopupMenuForItem.

Parameters

item	The item under the right-click.

Reimplemented in IlvDvProjectView.

rightClickOnItem()

virtual void IlvDvTreeView::rightClickOnItem ( IlvTreeGadgetItem *  item, const IlvPoint &  pt  )

protectedvirtual

Called when the user right-clicks a tree gadget item.

By default, it gets a popup menu by calling method getPopupMenuForItem and then displays it.

Parameters

item	The item under the right-click.
pt	The position of the mouse when the right-click occurs.
