wxAUI: Can't "Show" a closed pane (simple example enclosed)

[Fred Cailleau-Lepetit]

Hi,

for the left pane, try with this code on the constructor of your frame.

wxTextCtrl *p = new wxTextCtrl(this, -1, wxT("pane"));
    m_mgr.AddPane(p, wxAuiPaneInfo().Name(wxT("pane")).
       Caption(wxT("Pane")).DestroyOnClose(false).Left());

Regards
