SavePerspective/LoadPerspective

[Exhumer]

I'm using wxWidgets 2.7.2 and wxAUI shipped with it. Both compiled as DLLs.
I've a main frame managed by wxAuiManager. I need to save layout of panes on exit and restore it on next start. So, I'm calls wxAuiManager::SavePerspective in the destructor of the main frame, before wxAuiManager::UnInit(). And calls wxAuiManager::LoadPerspective in the constructor, after wxAuiManager::SetManagedWindow and all panes created. The string seems good, but LoadPerspective also returns false and all panes disappear.
How can I check what is wrong?

I found that value of the "name" in the load/save string is differ in each session.

Code: Select all

"layout1|name=<value>;...

That's why loading fails. The value seems like random set of digits. Any ideas?

If you don't specify a name with the wxPaneInfo::Name() method, there's no way that LoadPerspective/SavePerspective() can associate your pane info with a window pointer, because window pointers (and much of the time window ids) are different each time you run. You need to add panes with names, like the wxaui sample does.

After this your LoadPerspective() call will work.

Thanks a lot! Fixed it now.
But seems that this tip should be reflected in docs, because it's not evident.

Agreed!

It appears that the example code doesn't set the AuiPaneInfo anymore, so the above mentioned problem occurs when attempting to use the perspective saving/loading.

Just for anyone who stumbles along this post, here's an example of what you would change to get it to work.

Replace

Code: Select all

   m_mgr.AddPane(text1, wxLEFT, wxT("Pane Number One"));
   m_mgr.AddPane(text2, wxBOTTOM, wxT("Pane Number Two"));
   m_mgr.AddPane(text3, wxCENTER);

With

Code: Select all

   m_mgr.AddPane(text1, wxAuiPaneInfo().Name("Text1").Left().Caption("Pane Number One"));
   m_mgr.AddPane(text2, wxAuiPaneInfo().Name("Text2").Bottom().Caption("Pane Number Two"));
   m_mgr.AddPane(text3, wxAuiPaneInfo().Name("Text3").Center());

This was my issue. I kept of believing it knew what I wanted it to do, when I actually had to tell it.
