Hi all,
Are there any documentation or examples about event handling, list of
available event for each class... ?
Basically I want a QSTextField to accept only int values, ie checking
that only numbers are being typed in and that there is no overflow. Is
there anything built-in to handle that or do I have to implement it
myself with event listeners ?
You can use a QxSpinner instead. It does also support ranges for integer
values.
Otherwise you need to implement it your own. Probably in a seperate
class which you can contribute to the community?
I used to write it very simply in standard javascript with a keypress
event handler returning false if last typed character was not a number
or if it throwed an overflow exception... How can you do it with QooXdoo ?
In my opinion keypress is general a bad idea to handle this stuff
because there are many actions like insert, cut, copy which you couldn't
handle with this method. In qooxdoo you have a "input" event which is
much more advanced than a simple keypress.
yourTextField.addEventListener("input", function(e) {
this.setValue(parseInt(this.getRuntimeValue()));
});
Hope this helps.
Sebastian
Thanks,
