Button with lost focus using PerspectiveTrasnform - javafx-8

Well, I make a Pane based on an example of JavaFX samples (Display Shelf), I put Panes with Labels, Buttons, ComboBox, TableView where's the ImageView. It is working, when I click on Pane, it does the animation correctly, but the buttons that I put in vertical on Right of Pane, receive the focus out of where they are. When I move the mouse button, nothing happens, but if I move the mouse to down of it, I can click in the button that so reveice the focus. The local where I have to move the mouse to button to receive the focus is increasingly far (down) if the button is below the other.
I'm using the Perspective Transform of JavaEX and all is in JavaFX Samples, just changed some params of size (width and height). This effect may be interfering in focus? Or can be another problem? If anyone already had this problem please help me. Thanks.

How can I implement the native macOS screenshot mouse behavior?

I'm implementing a screenshotting app that captures a portion of the screen. I'm currently:
listening for a keyboard shortcut
drawing a transparent view on top of the entire screen
having the user click and drag to select an area inside of that view
screenshotting the coordinates inside of that bounding area.
Here's an example of what it looks like (the transparent view is tinted blue):
This works, but it causes the mouse to stop focusing on whatever it was previously focusing on. In other words, if I'm hovering over a tooltip and I hit the screenshot shortcut, the tooltip vanishes before I have a chance to screenshot it.
It looks like macOS's own screenshot command does not have this problem. If I hover over a date in StackOverflow in order to see the time tooltip, I can press Cmd+Shift+4 and screenshot it pretty easily:
If I try and do the same thing with my own code, the tooltip vanishes after I render my transparent view, even if I haven't moved my mouse.
Is Apple doing something specific to maintain the focus state of the mouse that I could be doing? Alternatively, should I somehow take advantage of Apple's own screenshotting flow myself inside of this app? If it helps, I'm currently using CGWindowListCreateImage to actually take the screenshot.

Unity Panel Interaction Issue

I have two panels in unity 2d directly overlapping each other and they use scroll panels so I can scroll down. I have it set so when one is accessed, the other is pulled up, but when they swap the other panel is grey and I cannot interact with it, but when I attempt to scroll the other panel scrolls instead, even though it is hidden and turned off.
I suspect that this is a bug in the code. It's possible, that when the user presses the scroll button in the first panel, and then releases the button, the second panel's scroll button thinks, it's already been pressed by the user, when in fact it isn't.
Set it up in such a way, that when you release the button on a scrollbar (the first scroll bar), it resets the click on the scrollbars connected to it (a second scroll bar).

Microsoft Access Combo Box Arrow Hidden Rectangle Reappears

I have a combo box on a continuous form. I don't want the arrow on the combo box to show unless the record is being changed. I accomplished this by placing a rectangle over the combo box arrow. This works great because it hides the arrow until the record is clicked, then the arrow shows.
The problem is that if you save the form design, close the form, and then open the form, the arrow will reappear and "stick" as you mouse over it. See image below.
The strange thing is that if you open the form, go into design view, and then go back to form view, it no longer "sticks".
Has anyone else had this problem, and if so have you found a work-around?
I did more testing and it turns out there was a little "sliver" of the combobox arrow button peaking out from behind the rectangle. When I expanded the rectangle to cover the entire arrow button, I no longer experienced this problem.

XCode 10 adding action to button

I'm trying to make a Cocoa app with buttons that run simple command line scripts.
I can't seem to figure out how to add the action to my button.
I've read some docs that suggest holding down option and dragging the button into controller code but I think they are out of date. Can someone suggest how to get there from this screenshot?
You need to first select your button, then hold the control ⌃ button on your keyboard and then drag that across to your view controller. That will then give you the option of what to name your method etc.
Actually I had the same problem and the root cause was just the drag method. From the descriptions I had assumed that I need to press CTL and then drag while having the left mouse button pressed. This did not work at all (in my environment). Then I noticed that "it works" with the right mouse button. But the result was not correct. (E.g. I could not get "Action"). Finally I found: I have to use the right mouse button only for dragging without holding CTL. Then I got the correct result.

GWT DnD: Keep draggable within an AbsolutePanel

I made a MultiSlider widget using the GWT and the gwt-dnd addon to rate texts. On the screenshot, you can see the slider button with value 50 dragged outside the slider bar. It can't be dropped outside the bar, but it can be dragged outside of it.

Is there a way in GWT to always keep the slider buttons inside the slider bar?
EDIT:
The slider bar is an AbsolutePanel, and it is also the only droptarget for the slider buttons. The slider bar panel is also the boundary panel for the drop controller. Dropping outside of the bar panel is not possible, but dragging is.
Now what I really like to know is if it's possible to keep the mouse pointer on the bar panel. If a button is dragged out of it, it will remain on its old position when dropped (so that's OK). Is it possible to allow only vertical DRAGGING? Can the mouse position be set while dragging?
I've used dragController.setConstrainWidgetToBoundaryPanel(true), and I think dragController.setBehaviorConstrainedToBoundaryPanel(true) does the same thing. For more information, check out the javadoc for your version.
The method you're looking for is defined in AbstractDragController with this signature;
void setBehaviorConstrainedToBoundaryPanel(boolean constrainedToBoundaryPanel);
The boundary panel (often passed in in the first parameter to the drag controller constructor) in this case should be an AbsolutePanel which wraps the slider.
It may also be helpful to visualize the absolute panel if things are not working as expected:
absolutePanel.getElement().getStyle().setProperty("border", "1px dashed red");
