trouble with shortcut commands

[skar karthikeyan]

Hi,

I'm trying to build a menu with shortcuts. Problem is, I can't link a
shortcut with a qx.ui.menu.RadioButton, but I can with a qx.ui.menu.Button.

Of course, I can manually set the "execute" listener for a shortcut
command to execute the same function as the radio group button's
handler, but I wanted to know if that is the only option?

Also, is there any way to support gmail like shortcuts, like say
pressing g and then i gets me to the inbox?

cheers,
skar.

That's interesting since both classes are sub-classes of
"qx.ui.menu.AbstractButton" which does include the "MExecuteable" mixin for
commands.

How do setup the command?

--snip--
var commandInstance = new qx.event.Command();
var menuRadioButtonInstance.setCommand(commandInstance);
--snip--

This should do the job.

Yepp, there is shortcut support. This is the first parameter of the
"qx.event.Command" class.

See

        http://demo.qooxdoo.org/current/apiviewer/#qx.event.Command

for details.

Thanks for the snippet :)

I did the following and the short cut "Ctrl+Alt+C" is shown if I click the Edit menu, but it doesn't show for the view menu. If I change the RadioButton to normal Button, now it shows.

main  : function() {
        // Call super class
        this.base(arguments);

        // Enable logging in debug variant
        if (qx.core.Variant.isSet("qx.debug", "on")) {
            // support native logging capabilities, e.g. Firebug for Firefox
            qx.log.appender.Native;
            // support additional cross-browser console. Press F7 to toggle visibility
            qx.log.appender.Console;
        }

        APP =  this;
        APPROOT =  this.getRoot();
        var view_menu = new qx.ui.menu.Menu;
        var view = new qx.ui.menubar.Button("View", null, view_menu);
        var viewFixedCommand = new qx.ui.core.Command("Control+Alt+I");
        var viewFluidCommand = new qx.ui.core.Command("Control+Alt+U");

        this.fixedButton = new qx.ui.menu.RadioButton("fixed");
        this.fluidButton = new qx.ui.menu.RadioButton("fluid");
        this.fixedButton.setCommand(viewFixedCommand);
        this.fluidButton.setCommand(viewFluidCommand);
        view_menu.add(this.fixedButton);
        view_menu.add(this.fluidButton);


        var edit_menu = new qx.ui.menu.Menu;
        var edit = new qx.ui.menubar.Button("Edit", null, edit_menu);
        var copyCommand = new qx.ui.core.Command("Control+Alt+C");
        var pasteCommand = new qx.ui.core.Command("Control+Alt+V");

        this.copyButton = new qx.ui.menu.Button("copy",null,copyCommand);
        this.pasteButton = new qx.ui.menu.Button("paste",null,pasteCommand);
        //this.copyButton.setCommand(copyCommand);
        //this.pasteButton.setCommand(pasteCommand);
        edit_menu.add(this.copyButton);
        edit_menu.add(this.pasteButton);


        var menubar = new qx.ui.menubar.MenuBar;
        menubar.setPaddingRight(10);
        menubar.add(edit);
        menubar.add(view);
        APPROOT.add(menubar, {top:10, left: 10});

      }

Yepp, there is shortcut support. This is the first parameter of the 
"qx.event.Command" class.
  

Well, the command can only be a simultaneous pressing of Ctrl, Alt, Meta, Shift with one of the normal keys. I want it to be a sequence of 2 commands, like g followed by i in case of gmail to reach inbox. Same with GNU screen, emacs etc where a sequence of key presses can be used. I know it's tough to have it in a browser, but still wanted to check with you guys :)

cheers,
skar.

Seems you found a bug. Can you please file a report for this and attaching your
example for the playground?

Just a hint: if you work with RadioButtons you can group them with
"qx.ui.form.RadioGroup" to have only one selected.

Currently this is not supported in qooxdoo. If you like to see this feature in
qooxdoo you can also file a bug report for this. This helps us to keep an eye
on the feature/enhancement wishes.

The bug is at http://bugzilla.qooxdoo.org/show_bug.cgi?id=3037.

Yes, I did that too. For this example however, I didn't use it.

Meta, Shift with one of the normal keys. I want it to be a sequence of 2

Well, it isn't that important, so I'd like the devs work on something important. Existing shortcut is quite good enough IMHO.

cheers
skar.
