问题 Is there a way to dispatch MouseEvent , same as dispatchKeyEvent using the KeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventDispatcher(listener); that happens before the event transferred to the component ? I know I have 2 options 1) add mouse event to all compoenents recursive 2) use a transparent glasspane Does Java support this , or do I have to use the one of the options above? thank you 回答1: Have you tried java.awt.Component.dispatchEvent(AWTEvent) ? import java.awt.*;

Mimicking/faking a Mouse Click and Mouse Wheel using Qt

由 时间秒杀一切 提交于 2019-12-07 03:16:39
问题 How to mimic/fake a Mouse Click and Mouse Wheel using Qt? To be more specific, I want to click inside and outside the Qt application. Thanks in advance! 回答1: If you want to simulate clicks on widgets inside your application, check out QTestEventList: A QTestEventList can be populated with GUI events that can be stored as test data for later usage, or be replayed on any QWidget. It lets you perform keypresses and various mouse events, but no wheel. Regardless, the source code should give cues

HTML content only scrolls with scrollbar, not mouse wheel

由 百般思念 提交于 2019-12-07 01:38:37
问题 I have a <div> on my page with a fixed height, and overflow-y: scroll; set so that the content will scroll when it passes the bottom edge of the <div> . Nothing out of the ordinary. For some bizarre reason, the mouse wheel will only scroll the content if the cursor is over empty space in the <div> or if it's over the scrollbar itself. If the cursor happens to be over any of the text content in the <div> , the mouse wheel won't do anything. This happens in both Firefox and Chrome, so it isn't

Detecting Shift modifiers on MouseEvent generated from click in swing

由 こ雲淡風輕ζ 提交于 2019-12-07 00:04:19
问题 I'm handling some MouseEvent in a GUI application using Java Swing. Since now i was analyzing mouse events inside mousePressed method, only to determine if a left or right click happened. My code was: public void mousePressed(MouseEvent me) { if (me.getModifiers == InputEvent.BUTTON1_DOWN_MASK){ //left click }else if (me.getModifiers == InputEvent.BUTTON3_DOWN_MASK){ //right click } Now my application is becoming more complicated and I need also to check if Shift button was pressed while

How to properly scroll an overflowing div based on mouse position within its container

由 陌路散爱 提交于 2019-12-06 20:40:33
I am working on a small jQuery plugin that autoscrolls through a set of overflowing elements within a container div based on the mouse position within that container div. See the Demo Here The idea is for this plugin to be an improvement of something I wrote a while ago. See the autoscrolling navigation in the lower left here The old problem with this was that it jumps around when you mouseenter from anywhere but the bottom(javascript perspective) of the container div. Now everything is working fine with my plugin but when you mouseenter from the top it screws up from time to time(move your

How to make absolute positioned image area maps clickable with mouse?

由 本秂侑毒 提交于 2019-12-06 20:05:58
问题 I have several images positioned on top of each other using absolute positioning. These images are partially transparent, and have a html area and map to make only the visible parts clickable. In jQuery, I have attached mouse events to the area tags. This works well for one image: mouseenter and mouseleave fire only when the mapped part of the image is entered. The problem is that it only works for the top image. For all others, it doesn't fire events not does CSS hover work, because there is

When are tunneling and bubbling events useful in WPF?

由 ↘锁芯ラ 提交于 2019-12-06 19:23:45
问题 I understand how bubbling and tunneling works. However, i'm confused about using them. Here is why: I want to handle a mouse click event. To bubble it, there is MouseDown and, to tunnel it, there is PreviewMouseDown . However, MouseDown doesn't necessarily mean the user clicked the control. May be the user pressed the button and moved away from it to cancel the click. I wouldn't want to change anything if the button is not being clicked. So my question is, how are the Bubbling/Tunneling

问题 I have an element which is on top of another element. I want to capture the mouseover event with the bottom element, but when the mouse cursor is over the top element the bottom element is not receiving the mouseover events.
