Label under image in UIButton

别说谁变了你拦得住时间么 提交于 2019-12-17 08:05:10
问题 I'm trying to create a button which has some text beneath the icon (sorta like the app buttons) however it seems to be quite difficult to achieve. Any ideas how can I go about get the text to display below the image with a UIButton ? 回答1: Or you can just use this category: ObjC @interface UIButton (VerticalLayout) - (void)centerVerticallyWithPadding:(float)padding; - (void)centerVertically; @end @implementation UIButton (VerticalLayout) - (void)centerVerticallyWithPadding:(float)padding {

Objective C - loop to change label text

眉间皱痕 提交于 2019-12-17 07:51:47
问题 i have a loop that looks like this for(int x=0; x < 10; x++){ [testLabel setText:[self randomString]]; sleep(1); } The randomString is a method where it returns a random string from an array. I'm using sleep so it is actually possible to see the label being changed. The loop works fine but the label only gets updated after the last iteration from the loop. Does anyone know why this could be? And would there be a way to fix it? 回答1: Do not call sleep() Certainly not ever on the main thread and

How do I manually change the key labels in a legend in ggplot2

℡╲_俬逩灬. 提交于 2019-12-17 07:22:39
问题 I am preparing a plot for publication. I created a stacked box plot to show frequency of patients in each group who were some complicated accumulation of seronegatives versus not. The legend is using the labels from the data frame which are appropriate for us who are working on the project but no for publication. I want to change the names to something more rapidly understood by the reader. So for instance run the following script grp <- gl(n=4,k=20,labels=c("group a","group b","group c",

问题 How can I rotate xticklabels in matplotlib so that the spacing between each xticklabel is equal? For example with this code: import matplotlib.pyplot as plt import numpy as np # Data + parameters fontsize = 20 t = np.arange(0.0, 6.0, 1) xticklabels = ['Full', 'token emb', 'char emb', 'char LSTM', 'token LSTM', 'feed forward','ANN'] # Plotting fig = plt.figure(1) ax = fig.add_subplot(111) plt.plot(t, t) plt.xticks(range(0, len(t) + 1)) ax.tick_params(axis='both', which='major', labelsize

Update Tkinter Label from variable

独自空忆成欢 提交于 2019-12-17 06:38:17
问题 I wrote a Python script that does some task to generate, and then keep changing some text stored as a string variable. This works, and I can print the string each time it gets changed. I can get the Label to display the string for the first time, but it never updates. Here's my code: from tkinter import * outputText = 'Ready' counter = int(0) root = Tk() root.maxsize(400, 400) var = StringVar() l = Label(root, textvariable=var, anchor=NW, justify=LEFT, wraplength=398) l.pack() var.set

C# vertical label in a Windows Forms

白昼怎懂夜的黑 提交于 2019-12-17 06:14:06
问题 Is it possible to display a label vertically in a Windows Forms? 回答1: Labels are easy, all you have to do is override the Paint event and draw the text vertically. Do note that GDI is optimised for Drawing text horizontally. If you rotate text (even if you rotate through multiples of 90 degrees) it will looks notably worse. Perhaps the best thing to do is draw your text (or get a label to draw itself) onto a bitmap, then display the bitmap rotated. Some C# code for drawing a Custom Control

Label outside arc (Pie chart) d3.js

依然范特西╮ 提交于 2019-12-17 05:41:05
问题 I'm new to d3.js and I"m trying to make a Pie-chart with it. I have only one problem: I can't get my labels outside my arcs... The labels are positioned with arc.centroid arcs.append("svg:text") .attr("transform", function(d) { return "translate(" + arc.centroid(d) + ")"; }) .attr("text-anchor", "middle") Who can help me with this? 回答1: I can solve that problem - with trigonometry :). See fiddle: http://jsfiddle.net/nrabinowitz/GQDUS/ Basically, calling arc.centroid(d) returns an [x,y] array.
