Which icon sizes to use with a JFrame's setIconImages() method?

由 旧城冷巷雨未停 提交于 2019-11-27 06:37:55
问题 Does anyone know which icon sizes to use with the setIconImages() (PLURAL) method for a jFrame so that my app icons display well on all platforms and in all contexts (e.g., window icon, taskbar icon, alt-tab icon, etc.)? I've found an example that uses a 16px-by-16px and a 32px-by-32px image, but do I need to go any bigger? To test, I have also tried adding 64px and 128px versions to the List passed to setIconImages(), but these do not seem to be used on my Windows 7 machine. However, I

Calling functions from a Tkinter Frame to another

由 痴心易碎 提交于 2019-11-27 05:23:26
I have a page where I'll show some customers details. So I created a page called "customers details" with all the labels that I need and I set the text of these labels as variables. Too bad it doesn't work. The labels are created in the __init__ method so I can't "update" them, becouse the init is called only at the beginning. So what I thought is to create a new function that contains all the labels and I will call that function when I have the necessity...here's the problem. I'm not able to call a function in an other tk.Frame . The following code is a simplified version of the code. import

UIScreen MainScreen Bounds returning wrong size

由 浪子不回头ぞ 提交于 2019-11-27 03:55:43
So I created a new project with the latest version of XCode and tried to log the screen size of my app (to determine the device type for UI). I ran the following code from my iPhone 5: NSLog(@"%f", [[UIScreen mainScreen] bounds].size.height); This returned 480 , which is the screen size for the old iPhone family. I tried in the simulator and the same thing happened. Is there some property I have to enable in the project for it to recognize the screen size? This only happens for 5+ devices; if I run the game on my iPad, it recognizes the 1024 screen size. I know for a fact that this code has

when should I use JFrame.add(component) and JFrame.getContentPane().add(component) in java

由 淺唱寂寞╮ 提交于 2019-11-27 02:15:00
问题 Is there a difference between them and are there any conditions in which one should be used instead of the other? 回答1: From what I understand from Javadocs, JFrame.add calls the latter. It is a convenience method to get around the incompatibility between AWT's frame and Swings JFrame. From javadocs for JFrame: The JFrame class is slightly incompatible with Frame. Like all other JFC/Swing top-level containers, a JFrame contains a JRootPane as its only child. The content pane provided by the

How do I change the background of a Frame in Tkinter?

由 怎甘沉沦 提交于 2019-11-27 02:14:06
I have been creating an Email program using Tkinter, in Python 3.3. On various sites I have been seeing that the Frame widget can get a different background using Frame.config(background="color") . However, when I use this in my Frames it gives the following error: _tkinter.TclError: unknown option "-Background" It does not work when doing the following: frame = Frame(root, background="white") Or: frame = Frame(root) frame.config(bg="white") I can't figure it out. I would post my whole source code but I dont want it exposed on the internet, but the frame creation goes something like this:
