label

问题 I wrote a tkinter code, with a label. There was a variable in the label text. lab = Label(root, text = 'randomstrings', x, 'randomstrings') lab.pack() When I ran the code, it gave an error message here: , x, It said: positional argument follows keyword argument 回答1: You must put all label pieces together before passing them to the Label : Label(root, text = 'randomstrings' + str(x) + 'randomstrings', ...) or: Label(root, text = 'randomstrings{}randomstring'.format(x), ...) 回答2: Using commas

问题 I want to add an html formatted string on a vaadin label. The string comes from a database and goes straight to the label, it must be formatted with bold text, line breaks and some other fancy text things. I found a couple of solutions but those were for old version of vaadin, is there any way of doing this on vaadin flow? 回答1: You could add an HTML content to a label using: Label label = new Label(); label.getElement().setProperty("innerHTML","A new line should be created after this <br />

问题 This is my VERY first post so forgive my newness. I'm trying to make a GUI of a dice rolling game (2 x six-sided). Logic of the random rolls is working fine to console. Also in console I see that die number is mapping to correct image file, but I'm having trouble changing tkinter label images to the new corresponding images on every roll beyond the initial startup roll. On startup, it displays both die images correctly, but when I click "roll" button, both images from first roll just

问题 I have a small app that creates dynamically a panel that includes a table layout panel where there is a list box and a label. The question is how I'm gonna assign a timer in every label created dynamically and also how I'm gonna start the timer from 00:00? I have tried this code but only adds the timer to the last label in the last panel created: public Form1() { InitializeComponent(); p = new Panel(); p.Size = new System.Drawing.Size(360, 500); p.BorderStyle = BorderStyle.FixedSingle; p.Name

问题 I am using facet-wrap to show two variables ( a and b ) for four cities. I could group the plots based on the cities but can not show the legend for the variables (i.e., a and b ) using scale_color_discrete. ggplot() + geom_line(data=df, aes(x=year, y = a, group=city), colour="red",linetype = "longdash",show_guide = TRUE) + geom_line(data=df, aes(x=year, y = b, group=city), colour="blue", show_guide = TRUE) + scale_color_discrete(name="Scenarios",labels=c("a" ,"b")) + guides(color=guide

问题 I have the following spider plot: I would like to align the variable names (i.e., LABEL_A, LABEL_B, LABEL_C, LABEL_D, VISIT_NAME) such that it is outside the plot (not touching the plot). How do I do that? What I tried so far? plt.xticks(angles[:-1], df1, color='black', size=12, ha = 'center') What should I add to justify the label names /the label names should not tough the graph? Thanks in advance! 回答1: Adjust the horizontal alignment after you plotted the graph depending on the angle

问题 In order to make the static control background transparent, I did handle the WM_CTLCOLORSTATIC like this: // make label transparent case WM_CTLCOLORSTATIC: { HDC hdcStatic = (HDC) wParam; SetTextColor(hdcStatic, RGB(0,0,0)); SetBkMode(hdcStatic, TRANSPARENT); return (LRESULT)GetStockObject(NULL_BRUSH); } the label is created like this: LRESULT CALLBACK Win2Proc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam) { switch(msg) { case WM_CREATE: hTab3_label = CreateWindowW(L"Static", L"This is

问题 I'm coding a little stocks ticker displayer program with tkinter label and I need to merge in the same line text in red color and green color. How can I do that? If not, is there any other widget which I can do it with? 回答1: You cannot have multiple colors in a label. If you want multiple colors, use a one-line Text widget, or use a canvas with a text item. Here's a quick and dirty example using a text widget. It doesn't do smooth scrolling, doesn't use any real data, and leaks memory since I

问题 I'm trying to do something I feel is quite simple in the grand scheme of things, however I'm clearly missing something. What I have is a simple database named 'localcollection'. What I would like to do is sum up the dollar amount of a column named 'purprice', and setting it as the text of a label (label4). I've been finding variants of code throughout the last couple days that suggest different ways of achieving this. The majority of my digging suggest that using ExecuteScalar is what I want

问题 How do I change the font colors on the labels? For example, I'd like the labels for A to be white and the labels for B and C to be black. Also, I'd like to make the labels bold. Vintage <- c(201801,201801,201801,201802,201802,201802,201803,201803,201803) Grade <- c("A","B","C","A","B","C","A","B","C") OrigAmt <- c(3.5,0.884,0.606,6.31,2.31,1.12,6.80,1.90,1.05) freq <- c(70.2,17.7,12.1,64.7,23.7,11.5,69.8,19.5,10.8) dat <-as.tibble(as.data.frame(cbind(Vintage,Grade,OrigAmt,freq))) dat$OrigAmt
