mouseevent

On stage, I have a MovieClip named "mc" with a simple rectangle drawn inside. mc also has a Button child named "btn" which is another simple rectangle ( smaller than mc's rectangle obviously). Then I have this code on stage. function mcDown( _e:MouseEvent):void{ trace( "mc" ); } function btnClick( _e:MouseEvent):void{ trace( "btn" ); } mc.addEventListener( MouseEvent.MOUSE_DOWN, mcDown ); mc.btn.addEventListener( MouseEvent.CLICK, btnClick ); The problem I am having is when click the button, mcDown event is also triggered and traces both "mc" and "btn". How can I make it so that when I click

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. 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. You can do this by using global hooks . In order to use them you'll need to include some natives or try the same using JNI (see: wikipedia ). Two examples: http://kra.lc/blog/2011/07/java-global-system

As the title suggests, is there a way for a disabled widget to receive mouse events? I'm using QWidget::setEnabled() for changing the appearance of widgets but I still want to receive their mouse events. Thanks in advance :) You can do this with an event filter on the widget in question. See QObject::eventFilter() . Your implementation might look something like this: bool MainWindow::eventFilter(QObject *obj, QEvent *event) { if (ui->pushButton) { if (event->type() == QEvent::MouseButtonRelease) { qDebug() << "mouse button"; return true; } else { return false; } } else { // pass the event on

In Chapter 15 of Liang's Intro to Java Programming (7th ed.) , he introduces a program to make a (2-D) ball on a JPanel and enlarge it upon clicking enlarge/shrink buttons. I've modified the program so that it also 1) enlarges/shrinks the ball if the user clicks/option+clicks, 2) allows you to pick the color of the ball by pressing a button, and 3) allows you to move the circle by dragging it with your mouse. The last modification is what was giving me trouble for a while, because I wanted to center the ball at the beginning, but then allow the user to move the ball around with the mouse. The

Despite not being a proficient GUI programmer, I figured out how to use the pyqtgraph module's ImageView function to display an image that I can pan/zoom and click on to get precise pixel coordinates. The complete code is given below. The only problem is that ImageView can apparently only display a single-channel (monochrome) image. My question: How do I do EXACTLY the same thing as this program (ignoring histogram, norm, and ROI features, which I don't really need), but with the option to display a true color image (e.g., the original JPEG photo)? import numpy as np from pyqtgraph.Qt import
