@class wxClipboard
@wxheader{clipbrd.h}
- A class for manipulating the clipboard. Note that this is not compatible with
- the
- clipboard class from wxWidgets 1.xx, which has the same name but a different
- implementation.
+ A class for manipulating the clipboard.
- To use the clipboard, you call member functions of the global @b wxTheClipboard
- object.
+ To use the clipboard, you call member functions of the global
+ ::wxTheClipboard object.
- See also the @ref overview_wxdataobjectoverview for further information.
+ See the @ref overview_dataobject for further information.
- Call wxClipboard::Open to get ownership of the clipboard. If this operation
- returns @true, you
- now own the clipboard. Call wxClipboard::SetData to put data
- on the clipboard, or wxClipboard::GetData to
- retrieve data from the clipboard. Call wxClipboard::Close to close
- the clipboard and relinquish ownership. You should keep the clipboard open only
- momentarily.
+ Call wxClipboard::Open() to get ownership of the clipboard. If this
+ operation returns @true, you now own the clipboard. Call
+ wxClipboard::SetData() to put data on the clipboard, or
+ wxClipboard::GetData() to retrieve data from the clipboard. Call
+ wxClipboard::Close() to close the clipboard and relinquish ownership. You
+ should keep the clipboard open only momentarily.
For example:
@code
// Write some text to the clipboard
- if (wxTheClipboard-Open())
- {
- // This data objects are held by the clipboard,
+ if (wxTheClipboard->Open())
+ {
+ // This data objects are held by the clipboard,
// so do not delete them in the app.
- wxTheClipboard-SetData( new wxTextDataObject("Some text") );
- wxTheClipboard-Close();
- }
-
- // Read some text
- if (wxTheClipboard-Open())
- {
- if (wxTheClipboard-IsSupported( wxDF_TEXT ))
+ wxTheClipboard->SetData( new wxTextDataObject("Some text") );
+ wxTheClipboard->Close();
+ }
+
+ // Read some text
+ if (wxTheClipboard->Open())
+ {
+ if (wxTheClipboard->IsSupported( wxDF_TEXT ))
{
- wxTextDataObject data;
- wxTheClipboard-GetData( data );
- wxMessageBox( data.GetText() );
- }
- wxTheClipboard-Close();
- }
+ wxTextDataObject data;
+ wxTheClipboard->GetData( data );
+ wxMessageBox( data.GetText() );
+ }
+ wxTheClipboard->Close();
