mouseevent

问题 In my WPF application , I am using ListView GridView, and I implemented a functionality that is associated to mouse double click. Is there a way, or a control that distinguish between the mouse double click and mouse click?

问题 I have a little problem with the Qt class QGraphicsScene : To detect the current mouse coordinates I made a new class QGraphicsScenePlus with QGraphicsScene as the base class. I have already redefined the slot function mouseMoveEvent(QGraphicsSceneMouseEvent* event) and the received coordinates seem to be correct. Now I want to notify the parent QMainWindow class, where the QGraphicsScenePlus object is stored, whenever the mouse coordinates change. What is the best way to do this? I already

问题 I have made the UI/Editor you can see in the picture below. The Text is displayed by StyledText s. The black lines are custom borders that are in fact Label s with lines drawn on them. Now my goal is to provide a selection that allows the user to select the Control s to delete them or add others to them. The second image shows a example selection. So started with all kinds of MouseEvent s this is more complicated than I initially thought. When the MouseDown event is fired on any Control I am

问题 How can I detect mouse scroll and movement event on windows from c++ application even when the application itself is inactive (I mean minimized or hidden) I can get keyboard events for (int i = 8; i <= 190; i++) { if (GetAsyncKeyState(i) == -32767){ SaveLogs(i, "log.txt"); wcout << (wchar_t)i; } } ///... int SaveLogs(int key_stroke, char *file){ if ((key_stroke == 1) || (key_stroke == 2)) return 0; FILE *OUTPUT_FILE; OUTPUT_FILE = fopen(file, "a+"); /*cout << key_stroke << endl;*/ if (key

问题 I have 16 Jpanels that I want to be highlighted when I hover my mouse over them. I created the JPanels anonymously and then added them to a parent, and added a MouseListener to each of them. I then added a MouseListener to the parent. The thing is, now it just highlights the parent. How can I fix this? NOTE: Sometimes the JFrame doesn't show anything - you just have to keep running it until it does (usually takes 2-3 tries). Comment if it still isn't working after >5 tries. HighlightJPanels

问题 Using jquery, how would I send an iframe's window mousemove events back to its parent, and the parent will see the event with the mouse coordinates mapped to it's own window? Both the iframe and parent are on the same domain. 回答1: I solved this problem by overlaying the iframe with an absolutely positioned transparent div. This way, the parent always gets the mousemove events. 来源： https://stackoverflow.com/questions/9608474/how-do-you-send-a-mousemove-event-from-an-iframe-back-to-the-parent

问题 My question is referring onto this question. At the moment I am using this answer, but I still can trick that code, so the clearInterval won't stop. While holding my left mouse button I simple press the right one to open the contextmenu. Now the clearInterval wasn't called. If I add the contextmenu event to the clicker , with a clearInterval it does get called, but it won't clear the interval. See this demo 回答1: Add clearInterval() to the mousedown event: clicker.mousedown(function() {

问题 I'm using JChart2D for trace a values of a double array. I'm using ZoomableChart and I want get coordinates (x, y) of cursor when this stay over ZoomableChart in my code to show them in a JLabel and draw a vertical line. How can I get the coordinates of the cursor? How can I draw this line? 回答1: To get a point is easy. Add a MouseMotionListener to the ZoomableChart.
