textfield

问题 I am working on a solution that implements adding text to textboxes but I disable the normal key events and use a custom one.

Is there another way to disable key events on the input field for the ipad? 回答1: Maybe you

问题 I'm getting this error for a column that in the model is declared as TextField and in the database is a LONGTEXT, and the value I'm trying to insert is only 3KB long. AFAIK LONGTEXT theoretical limit is 2GB, so I don't know why the limitation or how to get around it. Any ideas?

问题 Is there anyway to get the outline (Vector Object) of the text of a TextField using as3 code? Or to draw the paths of the TextField characters as a graphic? I want to store them in an SVG file. 回答1: It doesn't look like there is an easy built-in way to do this.

问题 Can anyone point me in the right direction here. Im wanting to have say 2 textfields initially then the user will be able to click 'add' button and another 2 textfields will be displayed (this needs to be dynamic as the user could click once or a 100 times for example) 回答1: Since it's wicket, it should be Java...
