FlatDarkLaf JButton ignores setMargin()

[jjazzboss]

I use FlatDarkLaf on my Netbeans application, thanks for this great L&F, it works very well in general :-)

For some specific dialogs I need "small" OK JButtons. The default left/right margins around the text are too large in this case, and I'd like to change them.

myButton.setMargin() works when using the system L&F, but is ignored when using FlatDarkLaf.

I found the FlatLaf properties "Button.margin", I tried setting myButton.putClientProperty("Button.margin", new Insets(...)) but it is ignored as well.

What could I do ?

Thanks

setMargin isn't being ignored:

But there's two components to the spacing. One is the margin and one is the insets, which afaik come from the border.

As Marcel sad, margins are not ignored, but your problem is that buttons in FlatLaf have a minimum width of 72px.
You can disable minimum width for a single button:

myButton.putClientProperty( "JComponent.minimumWidth", 0 );

Or for the whole application:

UIManager.put( "Button.minimumWidth", 0 );

This question brings me to the idea to not apply minimum button width if button margins are changed...

@DevCharly Thanks for the minimumWidth tip!

Starting with FlatLaf 1.5, if button (or text component) margins are modified (JButton.setMargin(...)),
then the minimum width is no longer applied.
