问题 I need the simplest way to draw a line between to coordinates. Since this drawing line in my code will be repeated more than 200 times in a loop i need the easiest way. I'm drawing the lines in a AWT panel component. 回答1: If you want to switch to Swing you would use the JPanel and overwrite the paintComponent() method. import java.awt.Graphics; import javax.swing.JPanel; public class PanelWithLine extends JPanel { @Override protected void paintComponent(Graphics g) { super.paintComponent(g);

问题 Here is the code for a camera surveillance system. In the configuration_page.py file I'm getting the size of the window as 100x30 despite using self.showMaximized() and resizeEvent() . The widgets present in it are also showing the size as 640x480 . I'm particularly interested in retrieving the size of a widget named self.mid_frame in CameraDisplay class present in config.py file. Earlier I was facing the same issue in dashboard.py file but I found a workaround by explicitly passing width and

问题 I create my from, define my TextBoxes, and for my placeholder text I'm using the following code: $AssetText.Add_MouseClick({ $AssetText.text = “” }) $ErrorText.Add_MouseClick({ $ErrorText.text = “” }) $IssueText.Add_MouseClick({ $IssueText = “” }) $TestTagText.Add_MouseClick({ $TestTagText.text = “” }) $TroubleshootText.Add_MouseClick({ $TroubleshootText.text = “” }) $ResolutionText.Add_MouseClick({ $ResolutionText.text = “” }) It works to remove text from the TextBox, but if I type a fair

问题 I have a GridView and I want to add a bannerAd after the gridview scroll ends. The bannerAd is called from the dependency https://github.com/kmcgill88/admob_flutter. The code for the GridView is as follows Widget build(BuildContext context) { SystemChrome.setEnabledSystemUIOverlays([]); return WillPopScope( onWillPop: () async { return true; }, child: Scaffold( body: Container( decoration: BoxDecoration( gradient: LinearGradient( colors: [const Color(0xFFFEFEFE), const Color(0xFFFEFEFE)],

问题 I am trying to implement an undo feature by creating a stack of 2 subtypes. I have a stack of parent type UserEntry holding two child types Assign and RelEntry. Assign and RelEntry is both classes used to insert values (number and relationship) into a grid table. There is a method call to insert the values into the table as their respective subtypes for example assignToTable() and RelEntryToTable() . I am trying to use a polymorphic method that can call both of these subtypes from the parent

问题 I am making a calculator using tkinter and I wish to do the following: Disable keyboard input for the Entry widget so that the user can only input through the buttons. Even after disabling keyboard input for the Entry widget, I wish to be able to change the background and foreground of the widget. I wish to hide the console window because it is totally useless in the use of this calculator. I don't want to let the user resize the root window. How do I disallow the resizing of the root window?
