When I'm dragging an item from a tablewidget, what triggers the the drag events, is it the QTableWidget, or the QTableWidgetItem? Or, something all together different? I need to alter my mimeData when it gets selected and is being dragged to a list.
Ok, I figured out my problem:
It's the QTableWidget that triggers the event. The problem I was having was that I set setDragEnabled(True) after I was trying to use my overridden event function.

I am having issues creating an event inside a function.
My function calls a “Bind Event to On Destroyed”. When dragging out the Event node, I call Create Event. After dragging the output of my bind event actor into the Create Event “Object” input, I select “Create a matching event” from the dropdown.
Afterwards, a new custom event appears inside my function, let’s call it “RespawnEvent”:
Now, when I search for the event in my “Create Event” dropdown, it just doesn’t appear:
Is this a bug or am I doing something wrong here?
Thanks in advance!
I'm having difficulties using the Click trigger in google tag manager.
I want to setup a trigger to fire on a click event, only when the element class contain "scrollto".
But the thing is, it keeps firing up even when the "scrollto" class isn't part of the element I clicked on.
Here are a few screenshot I hope will help you understand the problem:
Thank you for your help,
Alexis
Ones you set up any click trigger you will get these events everytime a user makes a click but that doesnt mean the trigger it self is being fired. You can append the trigger to any tag and you ll see that if you click anywhere else the tag wont fire even when you see the event.
Hope it helps!
Instead of click classes contains scrollto,
Give click classes equals scrollto
I have an RCP application where I am creating a view which invokes an instance of the composite.Now my problem is I want to trigger one event as soon as I show the view/composite in the screen.
I tried with addFocusListner(),addMouseTrackListener(),addMouseListner()but unfortunately none of the them gets the control as I move my mouse pointer around the view.Is there any way we can solve it?
Just grab the control you have used to create view and add selection listener on it.
for example if treeViewer is used to create that view then:
treeViewer.setSelection(new StructuredSelection(element),true);
Ensure selection by this treeViewer.getControl.setFocus();
If you want to trigger an event after your view is in focus/launch then you should add a listener to that view e.g IPartListener2for that you need to create a class and implement IPartListener2 interface. you will get more information here
Also if you want only using mouse event then you need to add MouseMoveListener to your view so when mouse pointer on your when mouseMove will call.
e.g. control.addMouseMoveListener(this);
When i click on an <input type=text>, a list of old values appear. If I chose one of them with the mouse, the event "change" from jQuery doesn't trigger.
What event should/could I use to detect this?
You have to use oninput event, using jquery:
$('#myinput').on('input',function(){
//your code here
});
change will only trigger if field loose it's focus (blur event). And the term old values appear is browser feature that remembers form data for fields with same name. You can not trigger change event with that. You need an alternate event like paste , input.
$("#field").on("input DOMAttrModified paste",function(){
});
I'm not sure of event. You can try some though.
My application is using workflow designer rehosting to let end-users develop workflows. I have an Activity available that requires the user set some state. To accomplish this, in the designer I override Initialize(Activity) and show a form which I then use to set values in my Activity. This is for setting the state when the Activity is initially added. I also have a double click event handler in the designer in case they need to edit that state later.
I now have a situation where, depending on the values in the form, I may need to add or remove a child activity. I've been successful in adding the activity, but not always in getting it to show up in the designer.
When Initialize is called, there are no child activities. I may need to add a child Activity. At this point, it works fine and shows up in the designer. The problem happens when they edit it later by double clicking. In my designer, I override OnActivityChanged to detect this. I make the same call to add a child, however the designer is not getting updated. Oddly enough, when the situation is such that the child is removed, the view updates fine.
Stepping through with the debugger shows that I am adding a child activity to the Activities collection. Normally when I have problems updating the view, I can make a call to IComponentChangeService.OnComponentChanged, but I can't seem to find a way to make this work.
Any suggestions?
It looks like I needed to use RemoveActivities and InsertActivities in the designer. It seems as if the designer doesn't listen to list change events on the Activities list. Does anyone know if this is how it's supposed to work?
Have you tried this in your OnActivityChanged event handler?
TypeDescriptor.Refresh(e.Activity);
For my situation, I determined I needed to use RemoveActivities and InsertActivities.
