问题 I need to add checkboxes to a JTree. A custom TreeCellRenderer/TreeCellEditor seems like the right approach. So far I used the CheckBoxNodeRenderer approach in this webpage. It works OK except for two things: there's additional whitespace above + below the checkbox; I'd like to keep it the same as a regular JTree. I would like to distinguish between clicking on the checkbox itself (which should attempt to toggle the checkbox) and clicking on the text associated with the checkbox (which should

问题 I'm working on a programming task. I'm working in Python , and using Tkinter for our GUI. I cannot change language or GUI tool, nor can I use any additional packages (for example Tix ). I need to make a list of items to pull. The first thing I thought of was a check box. However, so far as I know, Tkinter does not have anything that supports a large number(100+) of check boxes. The number is not constant, and likely will be different with every run of the program. In their own frame, I have

问题 I am trying to make a standard check box for my iPhone app from a UIButton with a title and image. The button image changes between an "unchecked" image and a "checked" image. At first I tried subclassing UIButton but UIButton has no -init*** method to use in my -init method. What is the best way to do this? Thanks in advance. 回答1: You shouldn't need to subclass the UIButton class. By design, Objective-C favors composition over inheritance. UIButton is a subclass of UIControl , which has a

问题 I am using jQuery Uniform to style inputs/selects etcs. However, the checkbox has stopped working. I am appending data sent from an ajax call. Once it's loaded, I use $.uniform.update("input:checkbox") to update the new html. When attempting to (un)check the input it works only once.
