Re: [qooxdoo-devel] How to set the cursor into a text field revisited (renderer branch)

[Dietrich Streifert]

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.

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.
