Java Forum / GUI / January 2007JTextField - how to disable selecting text in this component?
Hi! Has anybody an idea, how to do it? I'll be lucky. Regards, dako > Hi! > > Has anybody an idea, how to do it? I'll be lucky. > > Regards, dako Have you tried JTextField.setEditable(false) ? If this isn't the problem could you try and make the problem a bit clearer? Mearvk mearvk napisal(a): > > Hi! > > [quoted text clipped - 8 lines] > > Mearvk OK, I'll try explain the problem more clearly :) even though I have't felt comfortable writing EN yet... I don't need to disable selecting the component for a while or ages..., but only text within the component. I hope, it's an enough discribe my problem. > mearvk napisal(a): >>> Hi! [quoted text clipped - 16 lines] > > I hope, it's an enough discribe my problem. setEnabled(false) and setEditable(false) are different and setEditable(false) would be what you want to prevent people from putting text in it. Disabling the component is done by setEnabled() which wasn't what Mearvk proposed to you.

I forgotten say I don't want to prevent component from puting text in it but only whilst selecting text in it. Is it imposible?

When the mouseDrag event fires inside the JTextField do something like return immediately or set the focus on the parent JComponent. You will want to catch keyboard input also. (Block things like ctrl+A, ctrl+C, shift+end and shift+home) I think it can be done but it will require some hacking and time. There may be a better way but this is what I can figure.

How about - an entirely different /strategy/ in following 'the path of least surprise' in the use of GUI components? It is nonsensical to allow editing of a text field, but disallow selecting the text (I would normally select the text simply to delete the content, but if this scheme were implemented - i'd need to hit 'del, del, del, del, ..oh heck I'll just use the software of their direct competitor, instead..'). Andrew T. Andrew Thompson napisal(a): > It is nonsensical to allow editing of a text field, but > disallow selecting the text.... Sorry, but I don't agree with you. It is't nonsensical. You should remember that necessity is the mother of invention. Apparently somebody needed the solution as well, because exist special method: jTextField_userStreet.setHighlighter(null); Regards, dako. mearvk napisal(a): > Try subclassing JTextField.

I've already known the solution thanks to John. I might try JTextField.setHighlighter(null) so the idea is redundant. Regards, dako > Hi! > > Has anybody an idea, how to do it?

That is the thing in comparision with rest of comments :) The highlighter sounded familiar but I did't think about the null :| Regards, dako > Hi John! > > Thx a lot!

The caret still moves, and text is still selected and can still be cut and pasted. I doubt this is the behavior you want. The key question is why do you want to allow typing but not selection? Is it to prevent cut/copy/paste? If so, remove the cut copy and paste actions from the action map of the JTextField. It is not always enough to say what you want. Sometimes you have to say why you want it in order from the proper solution to be offered. Jim S. SignatureRemove my extraneous mandibular appendages to reply via email.
