  • How to make a blue button with white text?

    - by Bonnie
    // Make text white... and background blue [myButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal]; [myButton setBackgroundColor:[UIColor blueColor]]; Should that make a button with white text... and a blue background? It doesn't.

  • How to mask an view with an black-white image?

    - by mystify
    I've heard that it's possible to mask views with black/white images, where black means fully transparent and white means view is visible. The big difference to clipsToBounds is that the view could be clipped in funny shapes like circles or stars. How could I do that?

  • Why would my Silverlight 4 Out-of-Browser application just display white?

    - by Edward Tanguay
    My Silverlight application works fine when running in a browser. But when I install it as an out-of-browser application, the Window frame comes up with an appropriate icon and title, but the content of the window is just white. It is in the start menu but when I close it and open again, it is still blank. I reproduced this on Windows 7 and Windows XP. What could be causing my silverlight application to show only white when running out-of-browser? Here are the settings I used:

  • Texture not rendering in correct order in xna 4?

    - by user1090751
    I am making a simple board game. In the game there is a fixed background called myTexture and others are textureGoat and textureTiger whicha are to be placed on top of the background(myTexture). But i am having problem that fourth and fifth component is not displaying however, the sixth component( i.e. myTexture) is appearing. Here is my code, please look at it protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.Green); // TODO: Add your drawing code here spriteBatch.Begin(SpriteSortMode.BackToFront, BlendState.AlphaBlend); //placing tiger spriteBatch.Draw(textureTiger, new Rectangle(22, 25, 50, 50), Color.White);//first component spriteBatch.Draw(textureTiger, new Rectangle(22, 407, 50, 50), Color.White);//second component spriteBatch.Draw(textureTiger, new Rectangle(422, 25, 50, 50), Color.White);//third component spriteBatch.Draw(textureTiger, new Rectangle(422, 407, 50, 50), Color.White);//fourth component //placing goat spriteBatch.Draw(textureGoat, new Rectangle(125, 110, 50, 50), Color.White);//fifth component //placing background spriteBatch.Draw(myTexture, new Rectangle(0, 0, 500, 500), Color.White);//sixth component spriteBatch.End(); base.Draw(gameTime); }

  • Should you create a class within a method?

    - by Amndeep7
    I have made a program using Java that is an implementation of this project: http://nifty.stanford.edu/2009/stone-random-art/sml/index.html. Essentially, you create a mathematical expression and, using the pixel coordinate as input, make a picture. After I initially implemented this in serial, I then implemented it in parallel due to the fact that if the picture size is too large or if the mathematical expression is too complex (especially considering the fact that I made the expression recursively), it takes a really long time. During this process, I realized that I needed two classes which implemented the Runnable interface as I had to put in parameters for the run method, which you aren't allowed to do directly. One of these classes ended up being a medium sized static inner class (not large enough to make an independent class file for it though). The other though, just needed a few parameters to determine some indexes and the size of the for loop that I was making run in parallel - here it is: class DataConversionRunnable implements Runnable { int jj, kk, w; DataConversionRunnable(int column, int matrix, int wid) { jj = column; kk = matrix; w = wid; } public void run() { for(int i = 0; i < w; i++) colorvals[kk][jj][i] = (int) ((raw[kk][jj][i] + 1.0) * 255 / 2.0); increaseCounter(); } } My question is should I make it a static inner class or can I just create it in a method? What is the general programming convention followed in this case?

  • Multi Seat Ubuntu 10.10

    - by JJ Mcfly
    Hi I was hoping to have a 2 seat setup. One will be for my TV just going to run Boxee. The other is for my main Desktop. I've been looking for a good guide to help me navigate this, I'd like to use ubuntu 10.10. I am assuming it's just a case of getting a box + 2 graphics adaptors and 2 usb mice and keyboards, one of which will be bluetooth for the TV. I can't seem to find much documentation on this idea. Can anyone point me in the right direction? Also I am assuming that this is all possible with a standard ubuntu install, but with some additional configuration. Thank you in advance for any advice you can offer me JJ Mcfly

  • How to fix White Screen of Death after updating iTunes?

    - by cust0s
    The other night I updated my iTunes to the latest version (through Software Update) when I came to turn on my computer I was greeted with the dreaded white screen of death. I use an early 2008 iMac 24". I've tried the basic things, unplugging/turning off accessories, trying to boot from the install disk, reseting pram, etc, etc. Still no luck and no change what-so-ever. All I've been able to ascertain that my keyboard still works (by ejecting). I should point out that I did recently replace my Hard drive with a Western Digital Black 500GB (though the computer is well out of warrenty) and I'm a little concerned that the problem could be the screen.

  • What are those white circles on the desktop in Gnome 3?

    - by monk
    I have Fedora 20 with GNOME 3.10.2. On the desktop background (i.e. where the wallpaper is), there are five small white circles centered at the very bottom of the screen. The first is filled, the others are not. I can click those circles, thereby changing which one is filled, like a radio button. I cannot for the life of me figure out what those circles are supposed to do, and it's starting to drive me crazy. Clicking and thus changing which circle is filled does nothing I can perceive, and there seems to be no configuration option anywhere that has anything to do with them. What are those things? Is there any way to get rid of them? Edit: I made a screenshot of my desktop with no programs running. You can see the dot/circle thingies at the bottom.

  • Background image for list view still shows white behind text for cells.

    - by MonkeyTroy
    I wanted to put a background image partially visible behind a list view. I created a list view in my nib with an image view behind it and made the list view background 20% opacity. This allows the background image to show thru but my text in the cells show a white background behind and if I create the cells in cellForRowAtIndexPath the cells have a white background too. I am creating and setting the cell textLabel and the detailTextLabel in the cellForRowAtIndexPath event. Not sure how to get rid of that, or if there is a better way to do the background image.

  • How to change a grouped UITableView cell's background to black (or non-white)?

    - by Meltemi
    Just want to make sure I'm not overlooking something obvious... It seems like it should be trivial to set the background color (black is fine) of a UITableView's cell to something other than white or completely transparent so that you can display your data with white text. However, with my attempts I lose the corners on my grouped table view and it all looks like crap. I've seen & understand the methods described by Matt Gallagher about customizing TableView cells with exotic gradients, etc. but wanted to be certain before heading down that path...

  • Selenium: How to enter white space as the value of a text field?

    - by Andrew
    I have a form text field that is being populated with a default value. I would like to clear the value and enter white space to assert that the expected validation occurs. I am using Selenium RC and the PHPUnit Selenium extension. How can I achieve this? Note: I have already tried doing these, but they do not work: $this->type('FirstName', " "); //spaces $this->type('FirstName', "\t"); //tab character They clear the value from the field, but they do not enter the white space into the field.

  • Matlab: How to find the right-most point of a white line within the imrect?

    - by mchlfchr
    i've got a question regarding the imrect() function, which is part of the image processing toolbox in MatLab. I'd like to find a starting point within an image. I use the imrect function for setting a region to limit and specify the lookup area, but I can't get the point where the ROI mask is getting back mapped to the original size of the image. As you can see on the image there is a specified rectangle (cyan-colored), which I want to inspect for the white line, especially the nearest point to the right edge of the rectangle. I experimentated with only looking up on the last column of the rectangle, but as I mentioned before, the re-mapping onto the global image coordinates failed. So in this example, the white point I'd like to get would be around (98,302) The original (x,y) coordinates are relevant, so a cropping of the image to the rectangle is not acceptable. So, do you have any ideas? Thanks for any helping comments. Kind regards,

  • How to get rid of this sliver of white between DIVs?

    - by George Edison
    I am currently having trouble getting rid of a sliver of white... Here is an example page: http://m.stackoverflow.quickmediasolutions.com/view_question.php?id=97969&site=serverfault As you can see, the answers have a sliver of white stuffed between the top of the 'button' and the content. Here is some relevant code: <!-- this is the top of the 'button' --> <div class='top'></div> <!-- right here is where the space is --> <div class='content'></div> .top { height: 5px; } .content { display: block; padding-left: 10px; }

  • Why is my hg workbench & Adobe Reader toolbar icon a blank white page?

    - by Zasurus
    On my work's PC (windows 7 32bit) all Adobe Reader and hg Workbench icons on the toolbar (and general shortcuts for hg workbench) are just white pages (with the top left corner folded over). If you right click on the toolbar icon then right click on "TortoiseHg Workbench"(for hg workbench) then "Properties" then the "Change Icon..." button is greyed out (same for "Adobe Reader X"). Also the "Target:" is "TortoiseHg 2.4.0 (x86)" and is greyed out also the "Open File Location" is greyed out. This is the same for both Hg Workbench and Adobe Reader and seems to be the only thing that connects them. I have tried reinstalling to no avail. I also have local admin rights on the PC. I finally I have tried the following following questions without any luck (they aren't quite relevant to my issue but close): Adobe Reader program icon and pdf icons don't appear in Windows 7 Adobe PDF icon disappeared? Encase my description isn't enough to understand the issue here is a screenshot. As you can see the Hg Workbench icon (far left) and a pdf open in Adobe Reader X (second icon to from the left) are both blank and the shortcut is mainly greyed out.
