Java: remove margin / padding on a JTabbedPane

阅读更多关于 Java: remove margin / padding on a JTabbedPane

I'd like to know how to remove the margins between my JtabbedPane and my JFrame content pane and between my JTabbedPane and its internal JPanel. I circled the margins I want to remove. the green line is here to show the gap between the jpanel inside the jtabbedpane. I tried to look at some method named setMargin but it doesn't exist on a JTabbedPane. I also checked the Hgap and Vgap (both = 0) on the different layout (root content pane, my jpanel, etc). So any suggestions are welcome. Thanks. . I can't post images yet. It is up to the look and feel to decide how much space is around components

CSS 2.1 spec: rationale for not collapsing margins of parent (when parent is float or has overflow other than visible)

阅读更多关于 CSS 2.1 spec: rationale for not collapsing margins of parent (when parent is float or has overflow other than visible)

The CSS 2.1 specification, section 8.3.1 on collapsing margins states: Margins of elements that establish new block formatting contexts (such as floats and elements with 'overflow' other than 'visible') do not collapse with their in-flow children. It took me a while to realize that the block formatting context is the context that is established by the parent and applied to the children, so that to make any difference, the float or overflow properties have to be adjusted on the parent element (rather than to the children). In the following code snippet, border heights of adjacent child div

CSS page headers - how to use print margins?

阅读更多关于 CSS page headers - how to use print margins?

I can get a header to print on each page, but I'm new to print margins. I thought the @page css would work, but it does not seem to affect page margins. If I set the margins on the body, it works on page one, but subsequent pages start the top margin at the default, putting the header over top of the text. <style> .header { position: fixed; top: 0; } @page { size: 11in 17in; margin-left: 1in; margin-right: 1in; margin-top: 1in; margin-bottom: 1in; } </style> <body> <span class=header>This is the header</span> This is the text of the document. (repeat until I get to page 2) </body> Printing

This question already has an answer here: MATLAB subplot margin 3 answers I am plotting two subplots (2x1) in one figure. I would like to remove all the spacing between two subplots and remove the xlable and xlabel ticks for the top subplot too. Also, I am trying to remove all the spacing outside the subplot. I try set(gca, 'LooseInset', get(gca,'TightInset')) But it doesn't work. Now I am removing those margins and labels manually, I have 60 figures need to be handled and doing all those manually is time consuming. Any better way to do it? Thanks. I also try the subtightplot, it helps to

Vertical margins disappear when parent is set to overflow:visible

阅读更多关于 Vertical margins disappear when parent is set to overflow:visible

Why do vertical margins disappear when the parent is set to overflow:visible? If it's set to overflow:hidden margins are visible again. It seems counterintuitive. I think I understand how overflow is supposed to work when content of an element can't fit into it, but I don't understand what is happening with the margins. Here's an example: ( http://jsfiddle.net/VrVc7/ ) #outer { background-color:#EEE; overflow:hidden; } #inner { margin: 30px; padding: 5px; background-color:#ABE; } <div id="outer"> <div id="inner">abc</div> </div> It's because of collapsing margins: If you have overflow: hidden,
