double-click

问题 I want to inherit the default TabControl and handle the event double-click TabItem Header. This is XAML file: <local:MyTabControl x:Class="MyTabControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:CustomizedTabControl" mc:Ignorable="d"> <local:MyTabControl

问题 I have tried to implement in Pyside the method described in How to distinguish between mouseReleaseEvent and mousedoubleClickEvent on QGrapnhicsScene, but I had to add a crufty flag to keep it from showing single click after the second button release in a double click. Is there a better way? import sys from PySide import QtGui, QtCore class Example(QtGui.QWidget): def __init__(self): super(Example, self).__init__() """an attempt to implement https://stackoverflow.com/questions/18021691/how-to

问题 I'm trying to catch single clicks and double clicks on my figure. As stated in another answer, the event contains event.dblclick which is False or True, at least in Version 1.4.2, so double clicks can be got. The only problem is that it's not easy to distinguish between a single click and a double click because when double-clicking the event gets fired twice. The first time it's with event.dblclick=False and the second time it's with event.dblclick=True . Is there any solution to this? I saw

问题 I need to do: I am using the normal auto-fill function in Excel (double click the dot on the side of a cell) to copy the contents to the sub cells, so in this case clicking the dot in Cell A1 will do this: I need a script that will repeat the process down the entire column, until there are no more values in the adjacent cell. 回答1: Presumably this is what you're looking for: Option Explicit Sub FillInTheBlanks() Dim StartCell As Range, EndCell As Range Set StartCell = ActiveCell Set EndCell =

问题 I'm writing a small GUI program. Everything works except that I want to recognize mouse double-clicks. However, I can't recognize mouse clicks (as such) at all, though I can click buttons and select code from a list. The following code is adapted from Ingo Maier's "The scala.swing package": import scala.swing._ import scala.swing.event._ object MouseTest extends SimpleGUIApplication { def top = new MainFrame { listenTo(this.mouse) // value mouse is not a member of scala.swing.MainFrame

问题 I am trying to detect a doubleclick on a random cell of a tableview. The detection of the doubleclick is not a problem but rather which cell has been doubleclicked. table.addEventFilter(MouseEvent.MOUSE_CLICKED, new EventHandler<MouseEvent>() { @Override public void handle(MouseEvent event) { if (event.getClickCount() > 1) { System.out.println("double clicked!"); TableCell c = (TableCell) event.getSource(); System.out.println("Cell text: " + c.getText()); } } }); This is how I'm building my

问题 I need to do something like Google Maps does (but in WPF ): when RightClick on the map I have a ContextMenu. when RightDoubleClicking I have the UnZoom action. So, apparently, this is a little difficult in WPF... After struggling and searching a lot, read people that compains that "we can't predict the future" (I ask myself how does Google predict it), I decided to "wait" SystemInformation.DoubleClickTime and only then display a contextMenu. Surely, this is not ideal, even human-observable,

问题 I have a JTable in which I want to call a function when a cell is double-clicked and call another function when the cell is triple-clicked. When the cell is triple-clicked I do not want to call the double-click-function. What I have right now is (mgrdAlarm is the JTable) : mgrdAlarm.addMouseListener(new MouseAdapter() { public void mouseClicked(MouseEvent e) { System.out.println("getClickCount() = " + e.getClickCount()); if (e.getClickCount()==2) { doubleClick(); System.out.println("Completed

问题 please consider the following code: #include <QWidget> #include <iostream> #include <QApplication> class Widget : public QWidget { public: void mousePressEvent(QMouseEvent* event) { std::cout << "mousePressEvent" < std::endl; } void mouseDoubleClickEvent(QMouseEvent* event) { std::cout << "mouseDoubleClickEvent" << std::endl; } }; int main(int argc, char** argv) { QApplication app(argc, argv); Widget w; w.show(); return app.exec(); } Every time I process double click, the output is:

问题 Since I'm using native libraries I have different JARs for 32bit and 64bit platforms. Now when there are two JVMs installed on the system, one 32bit and one 64bit I face this behaviour: Double clicking the 32bit JAR -> works Double clicking the 64bit JAR -> App doesn't start Starting the 32bit JAR from console -> Error: This Java instance does not support a 32-bit JVM.Please install the desired version. Starting the 64bit JAR from console -> works On Mac I can start the 32bit JAR from console
