:class:`~wx.lib.agw.shortcuteditor.ShortcutEditor` is a widget that allows the user to customize and change keyboard
shortcuts via a dialog. It can be used to edit :class:`wx.MenuItem` shortcuts or accelerators
defined in a :class:`AcceleratorTable`.
.. note::
:class:`ShortcutEditor` **requires** the minimum AGW version 0.9.3 or the current
SVN, for the various enhancements made to the :class:`~wx.lib.agw.hypertreelist.HyperTreeList`
and :class:`~wx.lib.agw.genericmessagedialog.GenericMessageDialog`
widgets.
Description
===========
:class:`ShortcutEditor` is a widget that allows the user to customize and change keyboard
shortcuts via a dialog. It can be used to edit :class:`wx.MenuItem` shortcuts or accelerators
defined in a :class:`AcceleratorTable`.
The interface itself is very much inpired by the GIMP shortcut editor:
http://graphicssoft.about.com/od/gimptutorials/tp/keyboard-shortcut-editor.htm
There are very few minor UI differences between :class:`ShortcutEditor` and the GIMP one,
although the behaviour should be pretty much equivalent.
Various features:
* Shortcuts are listed in a tree-like structure, pretty much reflecting a menu
hierarchy (as most of the time :class:`ShortcutEditor` is used to edit :class:`wx.MenuItem`
shortcuts);
* Accelerators defined via :class:`AcceleratorTable` are handled in a similar way;
* Support for I18N;
* Ability to restore default shortcuts/accelerators via a UI button;
* Possibility to send back the new/updated shortcuts to the original :class:`wx.MenuBar` or
the original :class:`AcceleratorTable`;
* Filters on the shortcuts label (case-insensitive);
* Basic help window with instructions (customizable via :meth:`~ShortcutEditor.SetHTMLHelpFile`), via
the ``Help`` button.
And a lot more. Check the demo for an almost complete review of the functionalities.
UI Interactions
===============
1. In the :class:`ShortcutEditor` dialog you can open sub-sections by clicking the small box
with a + sign in it next to each section name. In the screen grab, you can see I've
opened the *Options* sub-section as I'm going to add a keyboard shortcut to the
*OptionsItem 1* item.

:target: _static/images/sphinxdocs/ShortcutEditor_1.png
**Figure 1**
2. Now you need to scroll to the tool or command that you want to edit and click on it
to select it. When selected, the text for that tool in the *Shortcut* column changes
to read 'New accelerator...' and you can press the key or combination of keys you
want to assign as a shortcut.
.. figure:: _static/images/sphinxdocs/ShortcutEditor_2_thumb.png
:alt: Assign Shortcut
:figclass: floatcenter
:target: _static/images/sphinxdocs/ShortcutEditor_2.png
**Figure 2**
3. I've changed the *OptionsItem 1*'s keyboard shortcut to ``Shift+Ctrl+F`` by pressing
the ``Shift``, ``Ctrl`` and ``F`` keys simultaneously. If you want to remove a keyboard
shortcut from any tool or command, just click on it to select it and then when the
'New accelerator...' text displays, press the backspace key and the text will change
to 'Disabled'.
Once you're happy that your keyboard shortcuts are set up as you wish, simply click
the ``OK`` button.
.. figure:: _static/images/sphinxdocs/ShortcutEditor_3_thumb.png
:alt: Remove/Save Shortcuts
:figclass: floatcenter
:target: _static/images/sphinxdocs/ShortcutEditor_3.png
**Figure 3**
4. If you thought my choice of ``Shift+Ctrl+F`` was an odd selection, I chose it because
it was a keyboard combination that hadn't already been assigned to any tool or command.
If you try to assign a keyboard shortcut that is already in use, an alert will open
telling you what the shortcut is currently being used for. If you want to keep the
original shortcut, just click the ``Cancel`` button, otherwise click ``Reassign shortcut``
to make the shortcut apply to your new selection.

Base Functionalities
====================
There are basically three ways to populate the :class:`ShortcutEditor` dialog, depending on
your needs. These approaches can be combined if needed.
1) Use the :meth:`~ShortcutEditor.FromMenuBar` method: if you need to give your user the ability to edit
the various :class:`wx.MenuItem` shortcuts in your application, you can create :class:`ShortcutEditor`
in this way::
# Build your wx.MenuBar first!!!
# "self" is an instance of wx.TopLevelWindow
dlg = ShortcutEditor(self)
dlg.FromMenuBar(self)
# Here the user will make all the various modifications
# to the shortcuts
if dlg.ShowModal() == wx.ID_OK:
# Changes accepted, send back the new shortcuts to
# the TLW wx.MenuBar
dlg.ToMenuBar(self)
dlg.Destroy()
2) Use the :meth:`~ShortcutEditor.FromAcceleratorTable` method: if you need to give your user the ability to edit
the various accelerators you set via :class:`AcceleratorTable` in your application, you can
create :class:`ShortcutEditor` in this way::
# Build your wx.AcceleratorTable first!!!
# "accelTable" is a list of tuples (4 elements per tuple)
accelTable = []
# Every tuple is defined in this way:
for label, flags, keyCode, cmdID in my_accelerators:
# label: the string used to show the accelerator into the ShortcutEditor dialog
# flags: a bitmask of wx.ACCEL_ALT, wx.ACCEL_SHIFT, wx.ACCEL_CTRL, wx.ACCEL_CMD,
# or wx.ACCEL_NORMAL used to specify which modifier keys are held down
# keyCode: the keycode to be detected (i.e., ord('b'), wx.WXK_F10, etc...)
# cmdID: the menu or control command ID to use for the accelerator event.
accel_tuple = (label, flags, keyCode, cmdID)
accelTable.append(accel_tuple)
dlg = ShortcutEditor(self)
dlg.FromAcceleratorTable(accelTable)
# Here the user will make all the various modifications
# to the shortcuts
if dlg.ShowModal() == wx.ID_OK:
# Changes accepted, send back the new shortcuts to
# the window with the wx.AcceleratorTable:
dlg.ToAcceleratorTable(self)
dlg.Destroy()
3) Build your own hierarchy of shortcuts using :meth:`~ShortcutEditor.GetShortcutManager`::
dlg = ShortcutEditor(self)
manager = dlg.GetShortcutManager()
for label, accelerator, bitmap, help, cmdID in my_list:
shortcut = Shortcut(label, accelerator, bitmap, help, accelId=cmdID)
manager.AppendItem(shortcut)
dlg.ShowModal()
dlg.Destroy()
Usage
=====
Usage example::
import wx
import wx.lib.agw.shortcuteditor as SE
class MyFrame(wx.Frame):
def __init__(self, parent):
wx.Frame.__init__(self, parent, -1, "ShortcutEditor Demo")
bar = wx.MenuBar()
menu = wx.Menu()
menu.Append(101, "&Mercury", "This the text in the Statusbar")
menu.Append(102, "&Venus", "")
menu.Append(103, "&Earth", "You may select Earth too")
menu.AppendSeparator()
menu.Append(104, "&Close", "Close this frame")
bar.Append(menu, 'File')
self.SetMenuBar(bar)
dlg = SE.ShortcutEditor(self)
dlg.FromMenuBar(self)
if dlg.ShowModal() == wx.ID_OK:
# Changes accepted, send back the new shortcuts to the TLW wx.MenuBar
dlg.ToMenuBar(self)
dlg.Destroy()
# our normal wxApp-derived class, as usual
app = wx.App(0)
frame = MyFrame(None)
app.SetTopWindow(frame)
frame.Show()
app.MainLoop()
