label

问题 Currently I'm trying to emulate this example. This works fine, however it has got one big restraint: it only works when your input type is text. When you use another input type, let's say email, a basic string isn't valid, so the placeholder falls over the text. So in my eyes there are to solutions to this problem: Use type=text everywhere, which is kinda crappy, because on mobile phones for example you won't get the email-type keyboard. Use JavaScript to check if the input has a value. I

问题 I'm trying to get the label of some network resources mapped as drives. When I use DriveInfo.GetDrives(), local volumes have the VolumeLabel filled parameter as expected, but in network drives it is an empty string.

问题 Is it possible in MIPS to change during execution the value of a label, or to create a label with certain value? I ask this because when using the instruction lw $a0, label($s0) i want to increment the value of label +4 every time we loop, indicating the new memory address of the array. I am aware I can do lw $a0, label+4($s0) but the new value of label will not be stored. Any advise? 回答1: No. In MIPS you must have a constant outside the parentheses when dereferencing (poor wording). If it

问题 I have a plot I made with ggplot2 in R that I would like to add a horizontal text label to the y-axis. However, depending on the length of my text, R compresses my plot accordingly to create a fixed width image. However, I need the plots to be identical length and have identical starting and stopping positions (margins) no matter the text width. I tried changing the plot margins by overwriting the default ggplot2 theme elements like so: library(ggplot2) png(filename="sample.png", width=5600,

问题 I'm having problem with adjusting the width of the label to reflect current width of the window. When the window size changes I'd like label to fill the rest of the width that is left after other widgets in row consume width they need. Putting the label in a Frame and using grid_propagate(False) does not seem to work. Consider following code: import tkinter as tk import tkinter.ttk as ttk class PixelLabel(ttk.Frame): def __init__(self,master, w, h=20, *args, **kwargs): ''' creates label

问题 I have an iPad app I'm developing where a random number is generated when a user clicks a button, and it appears on a label over the button, so the user thinks that value is on the button. The user can click the button again to get another random number if they want it. Is there a way for me to allow a user to drag a number from a source (say, a label) to another label - so that instead of a user having to click the button a number of times to get the number they want, they can simply drag it
