问题 The objective is to draw a couple hundred thousand vertical lines to a window, for which reason I need a scroll bar, zooming out is not an option as the space separating each individual line is not even a pixel. I have taken the approach of using paint methods in a class and adding both the class and JScrollPane to a JFrame. Didn't work out which is why I took the approach of using the NetBeans JFrame Form. Basically, how do I implement my graphics method into the panel that has the scroll

问题 I write Xamarin UITest for Android app. In the app uses google map. Help me please, how to click on a marker on the map? 回答1: If you're building the app yourself, I suggest checking out backdoor methods. These are methods that you can build into the app and then call from the test. There are plenty of examples for Obj-C and Java apps. Here's an example for C# backdoor methods, which you'd put in either your MainActivity or AppDelegate classes: http://danatxamarin.com/2015/05/07/configuring

问题 I have randomly generated a reproducible example of range . And I wish that my input will store in the Global Environment ( selectednumbers ). So when I run the shinyApp , let's say I choose the slidebarInput between 1 and 100 , the verbatimTextOutput will shows (which I satisfied): [1] 1 2 3 6 8 11 15 17 20 21 22 27 But when I checked for the selectednumbers (Global Environment), it shows (which I don't want): [1] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 [21] 21 22 23 24 25 26 27

问题 I have the following code and want to do the following: Most important point: Once I clicked on the file and get its filepath, I want the GUI to quit because I would then just feed that path to another script ( another_script ) which I would then import My problems is that, after the script successfully prints the path of the selected file, the GUI does not kill itself and i cannot run another_script and I'm stuck in the terminal import sys from PySide2.QtWidgets import QApplication, QWidget,

问题 I'm trying to build out a custom dropdown menu that looks like this: I've managed to implement the ListTiles and Row of Buttons without the dropdown, but I'm not sure how to nest all of that within a dropdown menu class. This is what I've got so far: class HomePage extends StatelessWidget { @override Widget build(BuildContext context) { return Scaffold( drawer: Drawer(), body: SizedBox.expand( child: SingleChildScrollView( child: Column( crossAxisAlignment: CrossAxisAlignment.start, children:

问题 I have a question about the syncronisation between loading resources async and keeping the selected element to the correct loaded resource. To be pricise I have a listview with users and one panel with his profile. If I choose that user, the user is loaded from an webservice and after that his data are shown in that profile-panel. Loading a user can be a very expensive operation (time) so I tried so make that loading async to prevent to block the whole UI-thread. I wrote in the ItemChange

问题 Closed. This question needs debugging details. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 days ago . I am working on a gui transformations project and i am making use of the java swing timer. The prob is that I have multiple if statements in the actionPerformed method of a jbutton. When I execute the first if statement I update a value. But when it comes to the 2nd if statement, it does not enter it.
