I am using constraints handlers, and want to add a condition to check before if these constraints has not been added before creating it.

in the latest ADF UI, there doesn't appear to be a way to add an IF Condition Block and reference another Block in the pipeline upon Success. The Old UI worked seamlessly, but the new one just allows you to add a new block - but not one from the existing Pipeline.
We could add the new IF Condition block to the exist pipeline and reference it to other Block easily.
As we know in the Data factory, the default green arrow means Success:
When we add the If Condition block and reference to other block, we could click the green arrow and it will be bold. We can enter 'Delete' key to delete it：
Now we can reference the block to other block, please see bellow gif:
I think the new Data Factory UI also is simple and easy to use.
In WebStorm with Angular, the "Undefined binding" inspection will flag undefined events on elements. How do we permanently add specific exceptions to this? For example, in the following, the (touchstart) event gets flagged:
<button class="keypad-button" (touchstart)="onKeypadKeyPress($event, '1')">1</button>
But we use this (touchstart) event handler everywhere, in hundreds of files and projects. And we can't simply disable the inspection -- we want it to work normally everywhere else.
Is there a way to add this particular event to an exception list permanently, across all files across all projects? Or can we update WebStorm's definition of a valid element's events?
Please follow WEB-44387 for updates; for now, I can only suggest suppressing the inspection by adding <!--suppress AngularUndefinedBinding --> to the top of your file
I want to show and hide an implemented object if a user press the key "0" in jogl how can I do it?
Simply add a key listener into the focused component exactly as you would do with any Java software using AWT and Swing. If you use NEWT, you'll have to use a key listener too anyway.
Then implement the method keyReleased(KeyEvent), modify the value of a boolean field when 0 is released and look at this value in GLEventListener.display(GLAutoDrawable) to determine whether to show or hide your object.
My custom Eclipse editor overrides createAction, where it registers an IAction with the editor. Then, in editorContextMenuAboutToShow I add this action to the menu.
Everything works fine, in that the action appears on the context menu within the editor; and I'm able to invoke the action from the menu itself.
Now, I'd like to add a key binding for this action. So far, I've added three extensions to my plugin.xml: a command, a binding, and a context. I can actually see the command/binding/context show up in the keys preference.
As for binding the command to my action, I've passed the command id declared in plugin.xml as the parameter to setActionDefinitionId after creating the action itself in createActions.
Needless to say, the key binding doesn't invoke the action - hence this question. What steps am I missing?
In a TextEditor-based editor, I had to touch these places in order to provide an action with a key binding:
define a command, key binding and scope (as you did)
set the actionDefinitionId to match the command id (as you did)
after creating the action in createActions(), I had to call setAction( myAction.getActionDefinitionId(), myAction );
set the scope in initializeKeyBindingScopes() with setKeyBindingScopes( new String[]{ "org.example.myScope" } );
Does that help?
I can set up one or more event listeners this way:
number roiListener1=imgDsp.ImageDisplayAddEventListener("roi_changed:ROI_Changed1")
number roiListener2=imgDsp.ImageDisplayAddEventListener("roi_changed:ROI_Changed2")
To remove them, I would do this:
imgDsp.ImageDisplayRemoveEventListener(roiListener1)
imgDsp.ImageDisplayRemoveEventListener(roiListener2)
Is there a way to remove all existing listeners attached on an imageDisplay, without giving the listener variable names?
Thanks,
Good question, but no, there isn't.
Except, of course, if the imageDisplay itself gets destroyed, which will remove the linked listeneres automatically, unless they themselves are "held" in memory due to something else (like a member-variable image which is displayed, another listener etc.)
The easiest way to "deal" with listeners is to manage the IDs in a TagList, then one can simply iterate over all entries.
