\section{\class{wxDocParentFrame}}\label{wxdocparentframe}
|

|
|
|

|
|
The wxDocParentFrame class provides a default top-level frame for
|
||
|
|
applications using the document/view framework. This class can only be used for SDI (not MDI) parent frames.
|
||
|
|
|
||
|
|
It cooperates with the \helpref{wxView}{wxview}, \helpref{wxDocument}{wxdocument},
|
||
|
|
\rtfsp\helpref{wxDocManager}{wxdocmanager} and \helpref{wxDocTemplates}{wxdoctemplate} classes.
|
||
|
|
|
||
|
|
See the example application in {\tt samples/docview}.

Deletes all views and documents. If no user input cancelled the
|
||
|
|
operation, the function returns TRUE and the application will exit.
|
||
|
|
|
||
|
|
Since understanding how document/view clean-up takes place can be difficult,
|
||
|
|
the implementation of this function is shown below.

|
|
||
|
|
\begin{verbatim}
|
||
|
|
bool wxDocParentFrame::OnClose(void)
|
||
|
|
{
|
||
|
|
// Delete all views and documents
|
||
|
|
wxNode *node = docManager->GetDocuments().First();
|
||
|
|
while (node)
|
||
|
|
{
|
||
|
|
wxDocument *doc = (wxDocument *)node->Data();
|
||
|
|
wxNode *next = node->Next();
|
||
|
|
|
||
|
|
if (!doc->Close())
|
||
|
|
return FALSE;
|
||
|
|
|
||
|
|
// Implicitly deletes the document when the last
|
||
|
|
// view is removed (deleted)
|
||
|
|
doc->DeleteAllViews();
|
||
|
|
|
||
|
|
// Check document is deleted
|
||
|
|
if (docManager->GetDocuments().Member(doc))
|
||
|
|
delete doc;
|
||
|
|
|
||
|
|
// This assumes that documents are not connected in
|
||
|
|
// any way, i.e. deleting one document does NOT
|
||
|
|
// delete another.
|
||
|
|
node = next;
|
||
|
|
}
|
||
|
|
return TRUE;
|

}
