I am trying to use the following java class to add an image to a Jtable. It has worked properly.

How to get middlemouse click event in C++

由 岁酱吖の 提交于 2019-12-02 08:42:18
How can I respond to a middle mouse click in C++/OpenGL? I know it may have to do with the WM_MBUTTONDOWN event however I am completely clueless with using it. I am also unfamiliar with callback functions so if it has to be used, can it be thoroughly explained? Can anyone show me how to implement the code for middle mouse click event? You can try and implement the oldschool version with the WM_ commands, but I think it'll be a lot easier to use GLUT (since it really makes life with OpenGL easier). #include <GL/glut.h> void myMouseHandleFunction(int button, int state, int x, int y){ if(button=

问题 I've got a JTree with nodes made up of a JLabel and a JComboBox. What I want is that when clicked on, the selected JComboBox will expand, but it seems like the first click is being consumed by the JTree itself (?), so I have to click it twice. Here is the code I have: import java.awt.*; import java.awt.event.*; import java.util.*; import javax.swing.*; import javax.swing.UIManager.LookAndFeelInfo; import javax.swing.plaf.ColorUIResource; import javax.swing.tree.*; public class JComboBoxJTree

I have a button that will change from black to gray when you hover over, I do this with setRolloverIcon(ImageIcon); . Is there any easy way to make a boolean equals to true while the mouse cursor hovers over the JButton or would I have to use a MouseMotionListener to check the position of the mouse cursor?

Capturing mouse position outside of browser window?

由 不羁岁月 提交于 2019-12-02 06:47:36
问题 One major barrier to creating immersive experiences in the browser (using WebGL and similar) is the set of limitations placed on mouse control. For instance a first person shooter control scheme essentially requires the program to grab the mouse and re-center it so as to allow infinite movement in any direction for the cursor. This is a no-no because it would give the web programmer too much control. Hopefully one day we will see a plugin that allows a site to request permission to move the

Make Qlabel clickable or double clickable in Qt

由 主宰稳场 提交于 2019-12-02 06:31:54
I am beginner in Qt, now I want to make my label clickable, I have searched so much online, but no one gives my a real example of how they made it. So can someone teach me step by step? Now my basic thinking is creating a new .c file and new .h file respectively and then include them into my mainwindow.c and then connect it with the existing label in ui form. These are what I was trying to do, but can not make it. Hope someone can teach and better put the step picture in the command, thanks. Here is the clicklabel.h code: #ifndef CLICKEDLABEL_H #define CLICKEDLABEL_H #include <QWidget>

java console mouselistener

问题 I am trying to make a mouse recorder, I cant seem to get a mouse listener to work with a console, is this possable and how would I go about it Thanks. 回答1: Unless you wrote your own console that fired mouse events, I dont' think you're going to be able to do it. What widget are you going to register your mouselistener against otherwise? The console isn't a swing component, therefore, no swing events. 回答2: You can do this by using global hooks . In order to use them you'll need to include some
