RE: [Pythoncard-users] enable and check menu items

[Kevin A. <al...@se...>]

In order to make a menu item checkable, you need to specify that in the
.rsrc.py file. For example, I modified conversions.rsrc.py:

            { 'type':'Menu',
              'name':'mnuConvert',
              'label':'Convert',
              'items': [
                { 'type':'MenuItem',
                  'name':'menuConvertMorseCode',
                  'label':'Morse Code',
                  'checkable':1 },
                { 'type':'MenuItem',
                  'name':'menuConvertTemperature',
                  'label':'Temperature',
                  'checkable':1,
                  'checked':1} ]
              }

So, both 'Convert' menu items are checkable and I set 'Temperature' to be
checked when the application starts. I modified conversions.py, so that when
one of the items is checked, the other one is unchecked.

    def on_menuConvertMorseCode_select(self, menu, event):
        self.conversion = MorseCodeConversion(self.components)
        self.menuBar.setChecked('menuConvertMorseCode')
        self.menuBar.setChecked('menuConvertTemperature', 0)

    def on_menuConvertTemperature_select(self, menu, event):
        self.conversion = TemperatureConversion(self.components)
        self.menuBar.setChecked('menuConvertMorseCode', 0)
        self.menuBar.setChecked('menuConvertTemperature')

The defaults (specified in spec.py) are that menus are enabled, and menu
items are enabled, but not 'checkable', so the other samples run without
modifications. If you specify that a menu item is checkable and want it
checked you'll have to specify that, since the default is 0, which is why it
is specified for 'Temperature' above.
