Here is the patch
Hi Dietrich,
thank you for your patch. But I've found another, better solution. I
have added focus() and blur() methods to QxWidget. These reset the mouse
flag for the focus handling. Doing this the _visualizeFocus method will
to a focus() call like we need it here.
Was just committed to CVS.

Best regards...

OK I had a look through the sources and got (hopefully) the place
where the focus is set. It is in QxWidget.js:
proto._visualizeFocus = function()
{
if (!QxFocusManager.mouseFocus && this.getEnableElementFocus())
{
try {
this.getElement().focus();
} catch(ex) {};
};
this.setFocusState(QxConst.STATE_FOCUSED);
return true;
};
In symetry to the proto._visualizeBlur method I modified the
condition in the if statement to:
if (this.getEnableElementFocus())
And it does the trick! Yes! The focus appears as expected!
Ok, yes. But this is not the way to go.
QxFocusManager.mouseFocus is needed to omit a focus() call if you are
working with the mouse currently. We probably should change this in
QxTextField (overwrite) directly. Could you submit a patch?

I modified the Window_4 example in two ways:
1) the first text field has an event listener "beforeAppear" which
sets the focus to the field via setFocused(true).
2) the "Set Focus To First Field" button has an execute event
listener which sets the focus to the field via setFocused(true)
Both have no effect. This is for FireFox 1.5 and IE 6.
OK, I meant "appear", not "afterAppear". You can't use
"beforeAppear", because then the widget is not already available in
DOM.
I have currently no idea, how to fix this. Will probably not be
fixed with the next release. A timeout started with the appear event
could probably help.

I think this is really a bug.
Testcase is attached.

Hello List,
after all these changes to the event manager and the introduction
of the appearance stuff I've reached again the point where I want
to set the cursor into a QxTextField programatically.
The situation is as follows: I have a QxTextField in a QxWindow.
When the user does an action which displays the window, the
cursor should be positioned automatically to the first text
field. This is the behaviour I would normally expect in a modal
dialog.
Calling the setFocused(true) method on the text field does not
seem to have any effect. Please have a look at the Window_4 example.
I had a working (but ugly) code which seemed to do the trick but
after all these changes It doesn't work anymore in FireFox. With
this the caret was set to the end of the text in the text field.
proto._setCaretToEnd = function (control) {
if (control.createTextRange) {
var range = control.createTextRange();
range.collapse(false);
range.select();
}
else if (control.setSelectionRange) {
control.focus();
var length = control.value.length;
control.setSelectionRange(length, length);
}
};
proto._setCaretToStart = function(control) {
if (control.createTextRange) {
var range = control.createTextRange();
range.collapse(true);
range.select();
}
else if (control.setSelectionRange) {
control.focus();
control.setSelectionRange(0, 0);
}
};
proto._setFocus = function() {
try {
var el = this.getElement();
this._setCaretToEnd(el);
this.setFocused(true);
}
catch(err) {};
};
How can this be done? Is there a clean qooxdoo way of setting the
focus?
Thank you for your help.
You can normally use the setFocused(true) which is IMHO the best
way. One simple thing you must understand is, that a focus work
only for visible elements in qooxdoo and html. That means you can
attach a afterAppear event to the textField and try to
setFocused(true) there. I haven't already tried this before. Just
an first idea.
Sebastian
Best regards.
