Does Show/Hide of Panes work under wxWidgets 2.8.4?

[mdefreitas]

I am trying to get Hide/Show to work for panes. So far no luck. I looked at the Roadmap and it appears this function is not yet implemented? But then I see posts that indicate it might be:
viewtopic.php?f=15&t=167&p=467

Is this feature available under wxWidgets 2.8.4?

Thanks,
Marco

Hi,

Are you just trying to hide and show a pane? Try this:

Code: Select all

wxAuiPaneInfo& info = m_mgr.GetPane(wnd);
info.Hide();
m_mgr.Update();


All the best,
Ben

Hi,

Are you just trying to hide and show a pane?

Yes... I am trying to "Show" a pane that I closed with the "x" button on the pane's frame. I am using the code you suggest. Here is a complete small example that fails to work. I set up a center pane and then create a pane I want to hide/show on the left. I "x" the pane on the left, and then I use the pulldown menu to bring it back (the callback does the "Show"). This fails under both wxMSW and wxGTK.

Should that be

Code: Select all

wxAuiPaneInfo& pi = m_mgr.GetPane(wxT("pane"));

i.e. a reference to the pane rather than a copy?

Indeed it should be... Thanks Julian!

Thanks for the response Julian. I was having the same issue so I am glad you caught that!
