label

问题 I have to develop a cross platform app in Xamarin forms and its one of the requirements is to be able to drag and drop dynamically generated labels between different views on same UI (i.e. check the image).. I have generated the dynamic labels but I am not sure how to implement drag and drop functionality. Can anyone guide me regarding the best choice of controls here like the containers containing the labels? Also do I need to write separate code for implementing the drag and drop on Android

问题 I have different "*.asm" files that need to be included in the "main.asm" file. The problem I'm facing is that: In many files I have declared labels like "loop", "forLoop", "whileTag" etc... in the same way ( i.e. with the same name ) And when I try to %include "file1.asm" and %include "file2.asm" it gives me a compilation error. It says that I can't declare the same label twice ( i.e. file1.asm and file2.asm, both have "loopHere" label declared ). How do I solve this ? Thanks The problem

问题 Is there a way to draw a transparent text on form that has some controls? If I use TLabel control, it would always show behind controls on the form. 回答1: You cannot use a TLabel control, since it is not a windowed control, and therefore it will be hidden by every windowed child control of the form. You could use a TStaticText , which is indeed a windowed control (a STATIC control), but it will be a bit difficult to make it truly transparent, I'd suppose. You can use layered windows for this:

问题 I have a view with 3 dynamic labels inside it and I am trying to find a way to centre it vertically in a scroll view but when its dynamic labels are too large to fit on a page, make the text start from the top. What Xcode is doing at the moment is this: What I am trying to do is this: Any ideas about how to achieve this? Thanks. 回答1: You can accomplish this by embedding the labels in a stack view and embedding the stack view in a UIView. The label text will expand the stack view vertically,

问题 It seems that the Label has no Hint or ToolTip or Hovertext property. So what is the preferred method to show a hint, tooltip, or hover text when the Label is approached by the mouse? 回答1: You have to add a ToolTip control to your form first. Then you can set the text it should display for other controls. Here's a screenshot showing the designer after adding a ToolTip control which is named toolTip1 : 回答2: yourToolTip = new ToolTip(); //The below are optional, of course, yourToolTip

问题 I have fixed this by adding 'exportselection=False' to the listbox line. but if somebody could explain why the [0] is needed in the line 'my_listbox_1.curselection()[0]'. I would be grateful, if not no worries. from tkinter import * from tkinter import ttk my_window = Tk() frame_for_list1 = Frame(my_window, padx=20, pady=20) frame_for_list1.grid(row=0, column=0) frame_for_list2 = Frame(my_window, padx=20, pady=20) frame_for_list2.grid(row=0, column=1) my_listbox_1 = Listbox(frame_for_list1,

问题 I have created a python class which inherits Tk from tkinter library. I want to add a label with an image to it but it only works when I create a Photoimage as variable to 'self'. This code works: class HMIDrawer(Tk): def __init__(self): super().__init__() self.frame = Frame(self) self.img = PhotoImage(file='resources/platoontomtom_empty.png') self.label = Label(self.frame, image=self.img, bg='white') self.label.pack() self.frame.pack() self.mainloop() And this code doesn't work: class
