I'm currently using the cursor component with the raycaster to determine if an object in my scene is clicked:
<a-entity cursor="rayOrigin: mouse" raycaster="objects: .deck"></a-entity>
I'm able to successfully listen to click events in my object. The problem I'm facing now is that the event payload does not contain any mouse details. Specifically I was hoping to determine if the click was a left or right click. The payload I get for the click event looks like this:
I noticed the cursor component was emitting the event. The only way I can think of to do this is to duplicate the cursor component and modify it to emit mouse data as well.
I was wondering if there is a better way to do this.

I have an Echarts graph (similar to a network graph), which has many nodes and edges. When I put the mouse on a node, the adjacent edges and nodes will be highlighted, but how can I move the mouse The highlighting of these nodes is still maintained after leaving. In other words, I want to trigger and cancel the highlighting by clicking, rather than hovering over the mouse.
In your tooltip chart options, add the option trigger:
tooltip : {
triggerOn : 'click'
}
in my case using click, mouseout, highlight event worked.
I can't find way to avoid default mouse hover event. so set click and mouseout event callback.
When click event occur, save the node 'dataIndex'. And when mouseout event occur, emit 'highlight' event with 'dataIndex' (use dispatchAction api)
I have a simple parent widget that reimplements mousePressEvent/mouseReleaseEvent. The parent's child widgets use enterEvent/leaveEvent. When I hover the mouse over the child widgets, leaveEvent/enterEvent executes, but when I click and hold the mouse, mousePressEvent executes, but enterEvent/leaveEvent goes silent (in other words, no click and drag). Any ideas about what could be causing this?
If you press and hold down the mouse button on a widget then that widget grabs mouse events until you release the button. This is not a special feature of Qt, you can find similar behaviour in every other GUI APIs I know.
Take a look at the relevant part of the Qt documentation:
QWidget / Events:
mousePressEvent() is called when a mouse button is pressed while the
mouse cursor is inside the widget, or when the widget has grabbed the
mouse using grabMouse(). Pressing the mouse without releasing it is
effectively the same as calling grabMouse().
void QWidget::grabMouse ():
Grabs the mouse input. This widget receives all mouse events until
releaseMouse() is called; other widgets get no mouse events at all.
I am currently implementing squiggly in a flex application to enable spell checking. Due to certain requirements, I can not use SquigglyUI to hook onto my spark RichEditableText. I have successfully used com.adobe.linguistics.utils.TextTokenizer to tokenize and highlight mispelt words.
I would like to be able to let the user rightclick on a mispelled word and show a list of suggestions in the context menu using getSuggestions.
I have tried to attach a listener to my RichEditableText:
richtexteditor.addEventListener("rightClick", showSuggestions);
And this is my event handler:
private function showSuggestions(event:MouseEvent):void{
trace('hi there');
}
The problem is when debugging the application, I never get the trace in my console as the rightclick event is never dispatched. In addition, I need to detect the word the user has right clicked on. How can I go about doing this and how can I detect right clicks?
Cheers
All I had to do was add an event handler to the contextmenu property of the richeditable text:
richtexteditor.contextMenu.addEventListener(ContextMenuEvent.MENU_SELECT, doSomething);
r.addEventListener(MouseEvent.RIGHT_CLICK, listener)
This will listen for the right-click of the mouse (Flex4.5)
In flex, I am using the following:
mx:TextInput mouseOver="tester(event)"
It works fine. My pointer goes over the textInput and it calls the function. But when I click inside the textInput to enter some text( focus is on the textInput) and then move the mouse (not taking mouse pointer outside of the boundary of textinput), the mouseover event is not trigerred.
If I use click event, then even if I am entering text ( or the focus is on the textinput) and then click, it will call the function.
How can I call the tester function on mouseover when the focus is on textInput?
The mouseOver event fires when the mouse is moved over the control.
Maybe you want to try the mouseMove event which will fire every time the mouse moves?
Keep in mind that mouseEvents and focusEvents are not inherently related. I would expect the mouseOver event to fire when the mouse rolls over your textInput regardless of whether or not that textInput has the focus.
I have placed a few buttons in a Qgraphicsscene, but I don’t know how to navigate to the button from a keyboard.
How would I set the focus to a button from the keyboard?
I assume that you used QGraphicsScene::addWidget() to add the button to the scene? It gives you a proxy object back, QGraphicsProxyWidget *, which inherits QGraphicsItem::setFocus(). But remember that it needs to have set the ItemIsFocusable flag and needs to be visible and active as well.
Additionally (from the setFocus() documentation):
As a result of calling this function, this item will receive a focus in event with focusReason. If another item already has focus, that item will first receive a focus out event indicating that it has lost input focus.
