size

I have these radio buttons and they need android:width="X" and android:height"X" however, I do not know how to set these properties so that they adapt to a different screen size. Here is the code I'm using for my buttons: <RadioGroup android:layout_width="fill_parent" android:layout_height="50px" android:orientation="horizontal" android:checkedButton="@+id/first" android:id="@+id/states"> <RadioButton android:id="@+id/first" android:background="@drawable/button_radio" android:width="50px" android:height="50px" /> <RadioButton android:id="@+id/second" android:background="@drawable/button_radio"

I am trying to find the size of my window by using the winfo_geometry() function but it ends up returning 1x1+0+0 I have also tried winfo_height, winfo_width but i keep getting 1 CODE from tkinter import * root=Tk() root.geometry('400x600') print (root.winfo_width()) print (root.winfo_height()) print (root.winfo_geometry()) root.mainloop() You are trying to get the dimensions before the window has been rendered. Add a root.update() before the print s and it shows the correct dimensions. from Tkinter import * root=Tk() root.geometry('400x600') root.update() print (root.winfo_width()) print

I'm trying to create a matrix containing 2 708 000 000 elements. When I try to create a numpy array of this size it gives me a value error. Is there any way I can increase the maximum array size? a=np.arange(2708000000) ValueError Traceback (most recent call last) ValueError: Maximum allowed size exceeded You're trying to create an array with 2.7 billion entries. If you're running 64-bit numpy, at 8 bytes per entry, that would be 20 GB in all. So almost certainly you just ran out of memory on your machine. There is no general maximum array size in numpy. A ValueError indicates the size is too

This question already has an answer here: 'property: 0' or 'property: 0px' in CSS? 9 answers Googling for the answer to this question has proven difficult so I figured somebody here should know. Within CSS, I've seen zero pixels declared as simply '0' yet also as '0px'. mystyle { width: 0; } anotherstyle { width: 0px; } The minor problem with '0' is that if you change it to some non-zero value, you might forget to add the 'px'. And when making a value '0', you may forget to remove the 'px'. I want pure consistency in my code and little things like this drive me nuts. Does this really come down

I put my buttons in a JPane with GridLayout. Then I put JPanel into another JPanel with BoxLayout.Y_AXIS. I want buttons in the GridLayout to be square. I use tmp.setSize(30,30) and it does not work. I also try to use new GridLayout(X, Y, 4, 4) but I cannot figure out what X and Y are. So, what is the correct way to do this stuff? ADDED: I still cannot solve the problem. Here is the code of what I am trying to do: import javax.swing.*; import java.awt.*; public class PanelModel { public static void main(String[] args) { JFrame frame = new JFrame("Colored Trails"); frame

I have variables in MATLAB, I've checked their class using class() but I also want to know the size that they take in the memory. More accurately, I know that they are of double type, and I want to make sure that they are 32-bit double and not 64-bit. The version of the MATLAB I'm using is R2009b. You can use whos to obtain an array of structures that describe, amongst other things, the size in bytes of each variable. Note that a double is, by definition, 64-bit! I wrote a simple convenience function to handle just this problem. Usage is: >> x = ones(1000); >> ByteSize(x) 7.63 Mb I run R2007a,

I have a label that shows the file name .. I had to set AutoSize of the label to False for designing. So when the file name text got longer than label size.. it got cut like in the picture. label1.Size = new Size(200, 32); label1.AutoSize = false; How do I re-size the text automatically to fit the label size, when the text is longer than the label size? bnguyen82 You can use my code snippet below. System needs some loops to calculate the label's font based on text size. while(label1.Width < System.Windows.Forms.TextRenderer.MeasureText(label1.Text, new Font(label1.Font.FontFamily, label1.Font
