Make a cooler JList interface Content:1. The working principle of the drawing device.2. Replace the appearance of JList and JComboBox with a custom drawing.3. Let the new look respond to mouse events. With the swing system's MVC design concept, it's easy to replace different skins for components. This article mainly takes jlist and JComboBox as an example to expl

With the maturing of jfc/swing, it is no longer an "impossible task" to develop a GUI comparable to C + +. In addition to its rich interface components, the following excellent features make swing even more powerful. Swing is i

I have not mastered the right-click menu in some components for a long time, and I have always felt quite difficult (it really seems that I am stupid, but I am in a daze spirit, and I succeeded today, but it will be nice to understand it later. So let's take a look at it and share it with you. 1: define variables. Jlist; jpopupmenu; jmenuitem; jsonjradiobuttonmenuitem; jcheckboxmenuitem; jseparator; 2: Initialize member variables. Saving, no writing.

Scenario: You can enter a character in a list to dynamically filter the display of items in the list. Of course, all the items displayed dynamically contain characters entered by the user! Here, the implementation of the function is very simple, there is no moreComplex logic. It only provides some examples for learners. You can perform the extensions you need.[Relationship diagram ]: In Swing, to build your own components, the simplest thing is to inherit the existing components, and then perfor

1. Define JList 2. Add mouse Monitor on the JList object (MouseListener) 3. After the Click event is triggered, determine its position in the jlist, and then determine the number of hits, depending on the number of times to select the processing function. String data[] = {"Red", "Blue", "green"}; JList

The scrollrecttovisible function receives only one rectangle parameter, indicating which region you want to be visible. For jtable, obtain the required parameters in the following way: Int x = jtable1.getbounds (). X; Int y = jtable1.getrowheight () * rowindex; Int width = jtable1.getbounds (). width; Int Height

OK, I admit that the word "dynamic" is used a bit. Let's take a look at the effect and explain it first. There is nothing dynamic in the picture. In fact, the effect is that when the item is selected in this way, the selected blue background changes
