Hide/Remove a Toolbar

greg.lucas-smith · November 11, 2004, 2:05am

Hi all,

I have a problem hiding a toolbar.
My application is as such:

frame

    toolbar

    panel

     
  SplitterWindow.

When I use toolbar.Hide() to
remove the toolbar I need the splitter to expand to fill the space that
the toolbar has made free but I can’t find a way to make this happen. Hide
just leaves a big blank space at the top of the frame where the toolbar
used to be. I’ve tried a few things, a Refresh() on the frame, panel,
splitter and everything else inbetween with no result. The panel
has a Sizer which I tried a Layout() on. Nothing works - what am
I doing wrong?

Thanks

Bones

You will proabbly have to entirely remove the toolbar by calling frame.SetToolBar(None). Then you can either Destroy or Hide the toolbar.

This is what I use:

def toggleToolbar(self, event):
self.GetToolBar().Show(event.IsChecked())
self.SendSizeEvent()

self is the main window of the app (a subclass of wx.Frame). It is called from a checkable menu item.

The same works for the statusbar btw:

def toggleStatusBar(self, event):
self.GetStatusBar().Show(event.IsChecked())
self.SendSizeEvent()

Cheers, Frank

Thanks for your reply!

I tried your suggestion and the frame did change, but rather that
fill the gap at the top of the frame, it made the main window (the
splitter) bigger at the bottom (past the bottom edge of the frame) and
still left a big blank spot at the top. Is this because the toolbar
still exists and the frame is allowing for it?

Any other ideas?

Thanks,

Bones

Heres the code for the problem below, man this is frustrating!

self.SetToolBar(None)
self.toolbar.Show(False)
self.SendSizeEvent()

Where self is obviously the frame.

What happens if you remove the first line? So just:

self.toolbar.Show(False)
self.SendSizeEvent()

Cheers, Frank

Greg_Lucas-Smith · November 14, 2004, 12:13pm

Nothing happens. It doesn't even push the splitterwindow down as I
described. Could the splitter be controlling it's own starting
position? I thought the frame would do that, but obviously not! Any
other ideas?

Thanks for your suggestions, a combination of these and a:

wxLayoutAlgorithm().LayoutWindow(self, self.panel)

has done the job.

Here is a full example - press enter to make the toolbar hide and show:

import wx
from traceback import print_exc

class HideToolbarTest(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, -1, "ToolbarTest", size = (666,480), style = wx.DEFAULT_FRAME_STYLE)
        panel = wx.Panel(self, -1)
        self.panel = panel
        panel.SetSize(self.GetClientSize())
        panel.SetBackgroundColour(wx.NamedColour("WHITE"))
               toolbar = self.CreateToolBar( wx.TB_HORIZONTAL|wx.NO_BORDER|wx.TB_FLAT|wx.TB_TEXT)
        self.toolbar = toolbar
        toolbar.AddTool(101, wx.Bitmap("greg.bmp", wx.BITMAP_TYPE_BMP), wx.NullBitmap, False, "", "Help String", "Help String") toolbar.AddSeparator()
        toolbar.AddTool(102, wx.Bitmap("greg.bmp", wx.BITMAP_TYPE_BMP), wx.NullBitmap, False, "", "Help String", "Help String")
        self.Bind(wx.EVT_TOOL, self.ButtonPressed, id=101)
        self.Bind(wx.EVT_TOOL, self.ButtonPressed, id=102)
        toolbar.Realize()
        self.SetToolBar(toolbar)
               panel.Bind(wx.EVT_KEY_DOWN, self.OnKeyDown)
               self.Show(True)
           def ButtonPressed(self, event):
        print "hello"
           def OnKeyDown(self, evt):
        if evt.KeyCode() == wx.WXK_RETURN:
            if self.toolbar.IsShown():
                self.toolbar.Show(False)
            else:
                self.toolbar.Show(True)
            # this is the important bit - instruct the frame to recalculate its component locations
            wx.LayoutAlgorithm().LayoutWindow(self, self.panel)
       class MyApp(wx.App):
    def __init__(self, flag):
        wx.App.__init__(self, flag)
          def OnInit(self):
        frame = HideToolbarTest()
        self.SetTopWindow(frame)
        return True

def run():
    try:
        app = MyApp(False)
        app.MainLoop()
    except:
        print print_exc()
       if __name__ == '__main__':
    run()

Could you post a short, but complete, sample that demonstrates the problem?

Thanks, Frank

Robin,

Thanks for the update, but a question about the overhead of destroying/creating a toolbar everytime? The app I'm writing that inspired this question has quite a complex toolbar, when I do as you suggest there is a noticable flicker in the window. Is there any other way?

Yes. Don't allow the frame to manage the toolbar itself, (don't use CreateToolBar or SetToolBar.) Instead use a sizer to manage the size and placement of the toolbar and the panel yourself, and call sizer.Hide(toolbar) or sizer.Show(toolbar)

OK,

I've put the toolbar in a sizer with

sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(toolbar, 0, wx.ALIGN_TOP)

and now all of the buttons on the toolbar are inactive (not sending events). Any ideas? I've tried

wx.EVT_TOOL(self, 101, self.Function)
self.Bind(wx.EVT_TOOL, self.Func, id=101)

and for fun:

self.Bind(wx.EVT_TOOL_ENTER, self.Test, id=101)

All with no effect - the buttons appear on the screen but won't click or show any sign of being a button (or useful at all). I'm really trying here!
