Does Show/Hide of Panes work under wxWidgets 2.8.4?

Postby mdefreitas on Wed Aug 29, 2007 10:52 am

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

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.

Code: Select all
#include "wx/wx.h"
#include "wx/aui/aui.h"

//============================================
// Declare the application class
//============================================

class MyApp : public wxApp
{
public:
   virtual bool OnInit();
};

//============================================
// Declare the main frame class
//============================================

class MyFrame : public wxFrame
{
public:
   enum {
      ID_ShowPane = wxID_HIGHEST + 1,
   };

   MyFrame(const wxString& title);
   ~MyFrame();


private:
   void onExit(wxCommandEvent& event);
   void onShowPane(wxCommandEvent& event);

   wxAuiManager    m_mgr;

   // This class handles events
   DECLARE_EVENT_TABLE()
};

DECLARE_APP(MyApp)
IMPLEMENT_APP(MyApp)

//============================================
// MyApp::OnInit: Initialize the application
//============================================

bool MyApp::OnInit()
{
   MyFrame *frame = new MyFrame(wxT("My App"));
   SetTopWindow(frame);
   frame->Show(true);
   return true;
}

//============================================
//============================================
//===
//===   Implementation of MyFrame
//===
//============================================
//============================================

BEGIN_EVENT_TABLE(MyFrame, wxFrame)
   EVT_MENU(wxID_EXIT,  MyFrame::onExit)
   EVT_MENU(MyFrame::ID_ShowPane, MyFrame::onShowPane)
END_EVENT_TABLE()

//============================================
// MyFrame::MyFrame: Constructor.
//============================================

MyFrame::MyFrame(const wxString& title) :
   wxFrame(NULL, wxID_ANY, title)
{
   //~~~ Tell wxFrameManager to manage this frame

   m_mgr.SetManagedWindow(this);

   //~~~ Build the menubar

   wxMenuBar *menuBar = new wxMenuBar();

   wxMenu *fileMenu = new wxMenu;
   fileMenu->Append(wxID_EXIT, wxT("Exit"));

   wxMenu *viewMenu = new wxMenu;
   viewMenu->Append(ID_ShowPane, wxT("Show Pane"));

   menuBar->Append(fileMenu, wxT("&File"));
   menuBar->Append(viewMenu, wxT("&View"));

   SetMenuBar(menuBar);

   //~~~ Create a docked pane

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

   //~~~ Create a center pane

   wxTextCtrl *c = new wxTextCtrl(this, -1, wxT("Center"));
   m_mgr.AddPane(c, wxAuiPaneInfo().Name(wxT("center")).CenterPane());

   //~~~ Commit changes to wxAuiManager

   m_mgr.Update();
}

//============================================
// MyFrame::~MyFrame: Destructor.
//============================================

MyFrame::~MyFrame()
{
   m_mgr.UnInit();
}


//============================================
// MyFrame::onExit: Exit event handler
//============================================

void MyFrame::onExit(wxCommandEvent& event)
{
   Close();
}

//============================================
// MyFrame::onShowPane: Show the Navigator panel.
//============================================

void MyFrame::onShowPane(wxCommandEvent& event)
{
   wxAuiPaneInfo pi = m_mgr.GetPane(wxT("pane"));
   if (pi.IsOk()) {
      if (!pi.IsShown()) {
         pi.Show();
         m_mgr.Update();
      }
   }
}

Should that be

Code: Select all
wxAuiPaneInfo& pi = m_mgr.GetPane(wxT("pane"));


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