-Description
-===========
-
-The idea of `SwitcherDialog` is to make it easier to implement keyboard
-navigation in AUI and other applications that have multiple panes and
-tabs.
-
-A key combination with a modifier (such as ``Ctrl`` + ``Tab``) shows the
-dialog, and the user holds down the modifier whilst navigating with
-``Tab`` and arrow keys before releasing the modifier to dismiss the dialog
-and activate the selected pane.
-
-The switcher dialog is a multi-column menu with no scrolling, implemented
-by the `MultiColumnListCtrl` class. You can have headings for your items
-for logical grouping, and you can force a column break if you need to.
-
-The modifier used for invoking and dismissing the dialog can be customised,
-as can the colours, number of rows, and the key used for cycling through
-the items. So you can use different keys on different platforms if
-required (especially since ``Ctrl`` + ``Tab`` is reserved on some platforms).
-
-Items are shown as names and optional 16x16 images.
-
-
-Base Functionalities
-====================
-
-To use the dialog, you set up the items in a `SwitcherItems` object,
-before passing this to the `SwitcherDialog` instance.
-
-Call L{SwitcherItems.AddItem} and optionally L{SwitcherItems.AddGroup} to add items and headings. These
-functions take a label (to be displayed to the user), an identifying name,
-an integer id, and a bitmap. The name and id are purely for application-defined
-identification. You may also set a description to be displayed when each
-item is selected; and you can set a window pointer for convenience when
-activating the desired window after the dialog returns.
-
-Have created the dialog, you call `ShowModal()`, and if the return value is
-``wx.ID_OK``, retrieve the selection from the dialog and activate the pane.
-
-The sample code below shows a generic method of finding panes and notebook
-tabs within the current L{AuiManager}, and using the pane name or notebook
-tab position to display the pane.
-
-The only other code to add is a menu item with the desired accelerator,
-whose modifier matches the one you pass to L{SwitcherDialog.SetModifierKey}
-(the default being ``wx.WXK_CONTROL``).
-
-
-Usage
-=====
-
-Menu item::
-
- if wx.Platform == "__WXMAC__":
- switcherAccel = "Alt+Tab"
- elif wx.Platform == "__WXGTK__":
- switcherAccel = "Ctrl+/"
- else:
- switcherAccel = "Ctrl+Tab"
-
- view_menu.Append(ID_SwitchPane, _("S&witch Window...") + "\t" + switcherAccel)
-
-
-Event handler::
-
- def OnSwitchPane(self, event):
-
- items = SwitcherItems()
- items.SetRowCount(12)
-
- # Add the main windows and toolbars, in two separate columns
- # We'll use the item 'id' to store the notebook selection, or -1 if not a page
-
- for k in xrange(2):
- if k == 0:
- items.AddGroup(_("Main Windows"), "mainwindows")
- else:
- items.AddGroup(_("Toolbars"), "toolbars").BreakColumn()
-
- for pane in self._mgr.GetAllPanes():
- name = pane.name
- caption = pane.caption
-
- toolbar = isinstance(info.window, wx.ToolBar) or isinstance(info.window, aui.AuiToolBar)
- if caption and (toolBar and k == 1) or (not toolBar and k == 0):
- items.AddItem(caption, name, -1).SetWindow(pane.window)
-
- # Now add the wxAuiNotebook pages
-
- items.AddGroup(_("Notebook Pages"), "pages").BreakColumn()
-

-

-
- # Select the focused window
-
- idx = items.GetIndexForFocus()
- if idx != wx.NOT_FOUND:
- items.SetSelection(idx)
-
- if wx.Platform == "__WXMAC__":
- items.SetBackgroundColour(wx.WHITE)
-
- # Show the switcher dialog
-
- dlg = SwitcherDialog(items, wx.GetApp().GetTopWindow())
-
- # In GTK+ we can't use Ctrl+Tab; we use Ctrl+/ instead and tell the switcher
- # to treat / in the same was as tab (i.e. cycle through the names)
-
- if wx.Platform == "__WXGTK__":
- dlg.SetExtraNavigationKey(wxT('/'))
-
- if wx.Platform == "__WXMAC__":
- dlg.SetBackgroundColour(wx.WHITE)
- dlg.SetModifierKey(wx.WXK_ALT)
-

-
- if ans == wx.ID_OK and dlg.GetSelection() != -1:

-

-
- else:
- nb = item.GetWindow().GetParent()
- win = item.GetWindow();
- if isinstance(nb, aui.AuiNotebook):
- nb.SetSelection(item.GetId())
