I can easily set up HBox's spacing programmatically (through constructor or setter method), but how can I do it on Scene Builder? I can't seem to find a place where I can enter that information.
I use SceneBuilder 8.0, but I think the property is located in the same place in the previous versions.
With an HBox selected, expand the "Layout" pane on the right (below "Properties" and above "Code"); the spacing property is the second one down, after padding and in the "Internal" section, in that pane:

I've created a blank project, and added a toolbar to the main window. To it, I've added two "Textured Rounded Button[s]" from the object library. I've left one as-is, and the other I've customized by setting the image.
At runtime, they look correct, with the correct width automatically inferred:
However, this doesn't match the interface builder preview:
The button's width was set when it used to have the title "Textured Rounded", but it didn't readjust its width after removing the title and adding the icon.
It bugs me that my IB preview and runtime UI don't match. Of course, I can hand-tweak the button width, but that:
Suggests to me I'm doing it wrong
Is going to break in the future, similar to how my mis-configured toolbar buttons started looking wonky in Big Sur.
What's the correct way to add a button to a toolbar, in interface builder?
I am trying to use the auto size classes from the storyboard on xcode 7 to position UI elements in a controller. The problem that I'm running into is that when I try to use the "Add missing constraints" function (located at the bottom right corner of the console), it positions my UI elements correctly except for the last elements (pictures describe better). The first image below shows the storyboard file where I just want 3 buttons (stacked above eachother) to be the same width and length to be on the top right corner of any screen.
However, when I add constraints and run the simulations, it seems like the top two buttons are positioned correctly with the correct length and width but the third button is out of place (image below).
So my question is, am I forgetting a step to make all buttons position themselves? Or should I try to convert everything to a percentage and place UI elements based on the percentage of the screen (if so, how would I go about doing that)?
I've also tried adding another blank button (removing the button label) underneath the 3rd button and adding constraints like that but it didn't work for me. Let me know if you have any suggestions, thanks!
In you case, Autolayout the constraints you need to give to UIButton is 4 constrains.
Leading
Trailing
Width
Height
If you miss any of them, then surely you will get an error. So, what's your error is?
To the third UIButton, you have not given the height, while to the above two buttons you have given.
So, just remove the bottom constraint of UIButton and give the equal height to above UIButton.
FYI, never use Add Missing Constraints without any confirmation from your side.
Update:
Check this video to remove trailing or leading margin:

You can actually see the solution in action if you use the Preview screen while setting up your auto layout constraints. I just created a similar view and buttons and stepped through the process. I coloured the buttons and named them to make things obvious.
I added the three buttons. At this point, none of the buttons show up in the preview.
I then setup the auto layout constraints for Button1. If you want the buttons anchored to the top right, then you don't need to worry about the leading constraint. You need width, height, top, and trailing.
Now Button1 will snap to it's position in the top right corner of the preview screen.
Now do the same thing for Button2. Set width, height, top (vertical space to Button1), and trailing.
Button2 will now snap into place in the preview.
Now the same thing again for Button3. You anchored the first button to the top right of the screen. Then Button2 to the bottom of Button1 and the right edge of the screen. Then again for Button3. You could also align the edges of the 2nd and 3rd buttons, if you prefer that to trailing space.
Now you'll see in the preview that your buttons are correctly positioned, regardless of device.
As long as you specify height and width for each button, you don't need to worry about the left edge or the bottom edge of the screen at all. They each know to "stick" to the top right and they know what size to be.
** Note: If you're not familiar with the "Preview" option...
With your storyboard open, hold Option and select storyboard again to get another copy of the storyboard on the right side. Highlight the view controller you are interested in on the left side. On the right side, select the Preview option as shown below.
Now you have your storyboard and the preview side by side, so you can see the exact impact of any auto layout changes you make. You can also add or remove devices to the preview.
I have a splitpane created from FXML that consists of Three panes left to right. I want to be able to hide the rightmost pane but I can't find anything to hide it. If I turn of the visibility it hides the pane content. What I want is to temporarily hide it, so the pane is removed visually.
As a temporary workaround I move the divider to 100%, but this leaves the divider visible. Another side-effect is that if I resize the main window the divider doesn't stay at the rightmost position.
Any tips on hiding one pane in splitpane?
Or any tips on the best way to achieve this without splitpane(rightmost pane needs to be resizable when not hidden). General pointers to techniques/containers would be appreciated since I'm new to Java/JavaFX but not to programming :)
Seems I've found it, even thought it's not a plain hide/show deal. My splitpane is named "mainSplitPane", and the one I want to hide/show is the third. Upon initialization of the controller I retrieve the third pane and store it in "componentsPane".
Declared in controllerclass:
Node componentsPane;
Called in initialize method of the controllerclass:
componentsPane=mainSplitPane.getItems().get(2);
Code to hide:
mainSplitPane.getItems().remove(componentsPane);
And code to show:
mainSplitPane.getItems().add(2, componentsPane);
mainSplitPane.setDividerPosition(1, 0.8);
A side effect is that I have to set dividerposition since it's removed.
I'm working on Xcode version 4.4. Couldn't find the way how to change element's(UIView) size more precisely in storyboard. I can drag anchors of element, but It's difficult when elements are small.
Is there any way to change width and height of element by one pixel?
EDIT: Development environment is iOS(not Mac OS).
You can edit a view's position and size in the Size Inspector. Select the view you want to modify, then from the menu bar choose View > Utilities > Size Inspector.
In Interface Builder, you should be able to use the inspector to edit the object's properties.

Is it possible in GWT to set Menu Item text in two different alignments,what I mean to say is
I want my menu item's label to be left justified and its accelerator key to be right justified.
i.e,
Create Alt+Ctrl+C
Edit Shift+E
Optimize Ctrl+O
There's a "boolean asHTML" option when creating menu items, set that to true, then use CSS to left align and right align the text you want to align.
