Step 4: Adding a Browser
This step shows how to add a browser. You may use a control chooser to get the identifier of the control. You just have to use the value returned by the
show function as the identifier, in the same way you use the value returned by
IlvFileBrowser::show() to get a filename.
Here is the new code for the member function
doIt:
void
MakeNodeInteractor::doIt(IlvRect& size)
{
// the manager should actually be a grapher.
IlvGrapher* grapher = ILVDYNAMICCAST(IlvGrapher*, manager());
if (!grapher)
return;
// Creates the new IlvGraphicCOMAdapter object.
IlvControlBrowser cBrowser(getView());
const char* identifier = cBrowser.show();
if (!identifier)
identifier = DefaultIdentifier;
IlvGraphic* obj = new IlvGraphicCOMAdapter(size, identifier, getDisplay());
// Deselects the previous object(s) if any.
grapher->deSelect();
// Adds the new object as a node into the grapher.
grapher->addNode(obj, IlvTrue, grapher->getInsertionLayer());
// Selects it.
grapher->makeSelected(obj);
// Deals with the commands if needed.
if (grapher->isUndoEnabled())
grapher->addCommand(new IlvAddNodeCommand(grapher, obj,
grapher ->getInsertionLayer()));
}
The class
IlvControlBrowser is defined in the header file
ilviews/windows/cbrowser.h. You must add the library
oledlg.lib in order to be able to use this class.
