Catch double click in QTableView's unused area

由 ￡可爱￡侵袭症＋ 提交于 2020-04-07 06:55:46
问题 My application starts with an empty table, and I want to imlement different methods to add items. One should be by double-clicking the table's unused area (or "background") that is not occupied by any cells. When a cell is double-clicked, I want the default behavior. I've found way to do this by re-implementing QAbstractScrollArea::mouseDoubleClickEvent() method in my TestTable class: #include <QMouseEvent> #include <QTableView> class TestTable : public QTableView { Q_OBJECT signals: void

深入了解iPad上的MouseEvent

由 倖福魔咒の 提交于 2020-02-29 03:36:17
iPad上没有鼠标，所以手指在触发触摸事件（TouchEvent）的时候，系统也会产生出模拟的鼠标事件（MouseEvent）。 这对于普通网页的浏览需求而言，基本可以做到与PC端浏览器无明显差异。但是如果你正在做一款与用户有着强交互的WebAPP程序，比如一个html5小游戏或者图片处理工具什么的，那么依赖默认模拟恐怕不能满足产品的需求。 一个通常的建议是：在iPad上(或者说各个移动终端上)，你的WebAPP应该能处理好TouchEvent，而不再依赖于MouseEvent。 然而如果你的WebAPP需要同时面向PC和iPad两种平台的浏览器用户，而迫于时间或者人力配备你没法分别提供两种版本的时候。。。你也许有必要了解一下下面这些有关iPad上MouseEvent相关的细节，然后砍掉两个平台上有明显差异的一些花哨特性，这样才能做出一个较好地兼容两个平台的WebAPP。 在阅读下文前，我假设你已经熟悉PC浏览器上MouseEvent的运作，也对TouchEvent有了粗略的了解。如果你并不了解，那理解以下各个细节可能有困难。 safari只对可点击(clickable) 的HTML 元素才会产生MouseEvent 。这在ADC文档中也提到了。 什么叫可点击，ADC文档定义是只要HTML元素响应mousemove、mousedown、mouseup

Detect if mouse button is down

由 点点圈 提交于 2020-02-15 09:47:49
问题 I am new to c++ and I am trying to activate a line of code only when the left mouse button is held down. In this example, my code works but it seems that it just toggles it. When I click, it spams the H key then, when I click again, it stops. Currently I have this code: if ((GetKeyState(VK_LBUTTON))) { keybd_event(VkKeyScan('H'),0,0,0); Sleep ( 30 ); } Edit: I have inside the function: int WINAPI WinMain ( HINSTANCE hInst, HINSTANCE P, LPSTR CMD, int nShowCmd ); 回答1: Use this to determine if

Html5/Js canvas capturing mouse coords when it moves fast

由 天涯浪子 提交于 2020-02-12 05:26:05
问题 I have a canvas where I draw a curve. onmouseup lines are drawn based on that curve and connecting specific x-points for it. The problem is that if the mouse is moved fast , not all of its points are captured . var canvas; var ctx; function drawCanvas(popup) { var flag = false; canvas = document.querySelector(popup + " #canvasG"); ctx = canvas.getContext('2d'); var sketch = document.querySelector(popup + " #canvasD"); var sketch_style = getComputedStyle(sketch); canvas.width = parseInt(sketch

Sending a button press event for a second pointing device

由 假如想象 提交于 2020-02-06 09:50:46
问题 So I want to make left mouse clicks using another pointing device (that can be created with e.g. xinput create-master mouse ) but those clicks shouldn't give focus to windows. This is what I got so far: (Compile this code with gcc -lX11 -lXtst -lXext -o test test.c and move your mouse over e.g. text that is inside of a text editor like Kate) #include <X11/Xlib.h> // Simulate mouse click void click (Display *display, int button) { // Create and setting up the event XEvent event; event.xbutton
