  • Java2d: JPanel set background color not working

    - by Algorist
    I am having the below code. public VizCanvas(){ { this.setBackground(Color.black); this.setSize(400,400); } } It worked fine and displays the panel in black background. But when I implement the paint method, which does nothing, the color changes to default color i.e gray. I tried to set graphics.setColor() but it didn't help. Thank you.

  • Use jQuery to find div by background color

    - by maxsilver
    I'm trying to use jQuery to find the number of divs that are both visible, and have a background color of Green. (Normally I'd just add a class to the div, style it green, and check for that class in jQuery but in this instance, I can't actually change the markup of the page itself in any way) I currently have the visible div part working as : if( // if there are more than one visible div $('div.progressContainer:visible').length > 0 ){ I'd like to throw some kind of "and background color is green" selector in there. // not legit javascript if( // if there are more than one visible div, and its color is green $('div.progressContainer:visible[background-color:green]').length > 0 ){ Is it possible to do this?

  • Calculating the average color between two colors in PHP, using an index number as reference value

    - by Roel Krottje
    Hi all! In PHP, I am trying to calculate the average color (in hex) between to different hex colors.. However, I also need to be able to supply an index number between 0.0 and 1.0. So for example: I have $color1 = "#ffffff" and $color2 = "#0066CC" .. If I would write a function to get the average color and I would supply 0.0 as the index number, the function would need to return "#ffffff". If I would supply 1.0 as the index number, the function would need to return "#0066CC".. However if I would supply 0.2, the function would need to return an average color between the two colors, but still closer to color1 than to color2.. If I would supply index number 0.5, I would get the exact average color of both colors.. I have been trying to accomplish this for several days now but I can't seem to figure it out..! Any help would therefor be greatly appreciated!.. Thanks!

  • HTML <select> selected option background-color CSS style

    - by arieltools
    Is there a style for a select option's "selected" color? For example: <HTML> <BODY> <FORM NAME="form1"> <SELECT NAME="mySelect" SIZE="7" style="background-color:red;"> <OPTION>Test 1 <OPTION>Test 2 <OPTION>Test 3 <OPTION>Test 4 <OPTION>Test 5 <OPTION>Test 6 <OPTION>Test 7 </SELECT> </FORM> </BODY> </HTML> When I select an option it turns blue, I want to override this and make it a different color. In the style I expected something like "selected-color", but it doesn't exist.

  • Graph coloring Algorithm

    - by Amitd
    From wiki In its simplest form, it is a way of coloring the vertices of a graph such that no two adjacent vertices share the same color; this is called a vertex coloring. Similarly, an edge coloring assigns a color to each edge so that no two adjacent edges share the same color, and a face coloring of a planar graph assigns a color to each face or region so that no two faces that share a boundary have the same color. Given 'n' colors and m vertices, how easily can a graph coloring algorithm be implemented? Lan

  • over Windows terminal change cursor width or color in Vim depending on mode

    - by INTPnerd
    I am using PuTTY to connect over SSH to an Ubuntu server from my Windows 7 workstation. Once connected I am using the Vim installation from the Ubuntu server to edit files. I want the cursor to change when I go into and out of insert mode. Part of my .vimrc file is like this but it is not changing the cursor: if &term =~ "xterm" echo "xTerm!!inate!" let &t_SI = "\<Esc>]12;purple\x7" let &t_EI = "\<Esc>]12;blue\x7" endif I know that the if statement is executing because of the echo. EDIT: Actually I would prefer to change the cursor to be a vertical line like you can in the PuTTY settings rather than change the color, or maybe even do both. But just changing the color would be a lot better than nothing. Also I am willing to change terminals if there is another Windows 7 Professionsal 64 bit compatible terminal that can do this (preferably something free). Maybe Poderosa can do this?

How can I change the color for these links only inside the element?

  • Color Temperature in PowerPoint 2010

    - by Otaku
    I'm teaching PowerPoint 2010 and it's got some great new features. Unfortunately, one that I can't wrap my head around is the the new "Color Temperature" feature for pictures. I do understand color temperature in general (i.e. the lower the number, the "colder"/"oranger" - the higher the number, the "hotter"/"bluer"). The way PowerPoint implements it seems opposite from most other programs - like Photo Filter in Photoshop. So I need to understand what this feature is in more detail so I can explain it to my students. Does anyone know?

  • Change the white background in webpages to another color

    - by Bruce Connor
    I'm currently using a dark theme in firefox. It looks really nice, but many webpages use a plain white background. The resulting contrast is a little unpleasant and sometimes hurts the eye when I switch from a dark tab to a white tab. Is there a way to make firefox replace white backgrouns everywhere with some other color (light gray, for instance)? It could be a Stylish script, a userChrome.css hack, or anything that works (preferably as light as possible). To make myself clear: after I achieve my objective, the background color whenever I visit the super-user site should be light-grey instead of white, and the same should happen to any other site with a white background (google sites, tech crunch, etc). Is there a way to do that?

  • Emacs/xterm color annoyance on Linux

    - by tgamblin
    I'm using emacs in a console window both on my local Linux box and on the login node of a remote cluster. I use emacs regularly, and I've got the foreground color set to white in my .emacs file like so: (set-foreground-color "white") (set-background-color "black") However, when I run emacs, the foreground isn't white; it's grey and very hard to read. On my Mac, emacs in a console window with the same settings shows up as proper white. But on both linux boxes, in konsole and xterm, it's grey. In case it matters, I've got TERM set to xterm-color, the desktop is running RHEL 5, and the cluster node is running RHEL 4 (CentOS). Is this some default with how Linux sets up terminal colors? How do I get white to be white? Note: this is with console emacs, not emacs under X. That's emacs -nw if you have DISPLAY set.

  • Blogger Template: how to change the color of the border css

    - by Lirik
    Hi, I'm trying to change the borders in the style sheet of the template on my blog, but I've never done anything with css so I'm a little bit at a loss... I want to keep the dark background, but I want to create a small border with a slightly different color around my postings. If my guess is correct, then I should modify some of these definitions: body { background:$bgcolor; margin:0; color:$textcolor; font: x-small "Trebuchet MS", Trebuchet, Verdana, Sans-serif; font-size/* */:/**/small; font-size: /**/small; text-align: center; } a:link { color:$linkcolor; text-decoration:none; } a:visited { color:$visitedlinkcolor; text-decoration:none; } a:hover { color:$titlecolor; text-decoration:underline; } a img { border-width:0; } Here is a pastie with the entire template I'm using: http://pastie.org/932535 Is there a quick way to achieve the desired effect? Your help is appreciated!

  • Visual Studio 2010 + Resharper Tools|Options|Environment|Fonts and Colors

    - by Gerard
    About fonts and colors in the VS2010 C# text editor with Resharper installed. In the following method: public void Method() { var lis = new System.Collections.ArrayList(); var exc = new System.NotImplementedException(); } ArrayList gets another color as NotImplementedException in the VS2010 text editor, because I edited the color scheme. What would be the difference in these kinds of types so that the color scheme handles them differently? Note that I have Resharper installed but I also tried almost all Resharper entries. I would like to have the ame color for both, but the color of the NotImplementedException type seems immutable.
