try this instead, reason what things didn’t quite work is that the context menu is in fact bound to the oncontextmenu event. function contextMenuClick(element){ var evt = element.ownerDocument.createEvent(‘MouseEvents’); var RIGHT_CLICK_BUTTON_CODE = 2; // the same for FF and IE evt.initMouseEvent(‘contextmenu’, true, true, element.ownerDocument.defaultView, 1, 0, 0, 0, 0, false, false, false, false, RIGHT_CLICK_BUTTON_CODE, null); if … Read more
TextBox Class TextBox has built-in handling for the bubbling MouseUp and MouseDown events. Consequently, custom event handlers that listen for MouseUp or MouseDown events from a TextBox will not be called. If you need to respond to these events, listen for the tunneling PreviewMouseUp and PreviewMouseDown events instead, or register the handlers with the HandledEventsToo … Read more
I would use a Button control and overwrite the Button.Template to just show the content directly. <ControlTemplate x:Key=”ContentOnlyTemplate” TargetType=”{x:Type Button}”> <ContentPresenter /> </ControlTemplate> <Button Template=”{StaticResource ContentOnlyTemplate}”> <Label Content=”Test”/> </Button>
What are the proper typescript types for addEventListener mousemove and it’s event argument? Being explicit will set you free: onMouseMove: { (event: MouseEvent): void } = (event: MouseEvent) => { } Or, let TypeScript infer it from assignment 🌹: onMouseMove = (event: MouseEvent) => { }
This is 2017 and the right answer is now: $(window).on(‘wheel’, function(event){ // deltaY obviously records vertical scroll, deltaX and deltaZ exist too if(event.originalEvent.deltaY < 0){ // wheeled up } else { // wheeled down } }); Works with current Firefox 51, Chrome 56, IE9+ Note: The value of the deltas will depend on the browser … Read more
Yes it is possible and pretty easy once you understand tkinter, here’s a quick script: from Tkinter import * from tkFileDialog import askopenfilename import Image, ImageTk if __name__ == “__main__”: root = Tk() #setting up a tkinter canvas with scrollbars frame = Frame(root, bd=2, relief=SUNKEN) frame.grid_rowconfigure(0, weight=1) frame.grid_columnconfigure(0, weight=1) xscroll = Scrollbar(frame, orient=HORIZONTAL) xscroll.grid(row=1, column=0, … Read more
For parity between desktop and touch you have the following equivalences: mousedown === touchstart mousemove === touchmove mouseup === touchend Thus if you handle mousedown, mousemove and mouseup then you don’t need to handle the corresponding equivalent events under touch. The same handlers should be executing.
You can use an event filter on the application. Define and implement bool MainWindow::eventFilter(QObject*, QEvent*). For example bool MainWindow::eventFilter(QObject *obj, QEvent *event) { if (event->type() == QEvent::MouseMove) { QMouseEvent *mouseEvent = static_cast<QMouseEvent*>(event); statusBar()->showMessage(QString(“Mouse move (%1,%2)”).arg(mouseEvent->pos().x()).arg(mouseEvent->pos().y())); } return false; } Install the event filter when the MainWindows is constructed (or somewhere else). For example MainWindow::MainWindow(…) { … Read more
<StackPanel Background=”Transparent” … > or <Border Background=”Transparent” … > should do the trick… This makes the grid transparent, however visible for mouse-clicks. Look here form more Information. There are some other circumstances, where you have to use the PreviewXXX– event, this is when a child element “swallows” the event away, but in your case, the … Read more
