clipboard

I have some Python code that edits image files and would like to know how to add image data to the Operating System clipboard and get it from there. When searching for a cross-platform solution to replace or get clipboard text in Python, there were many simple answers to do it (e.g. using the built-in Tkinter module with some code ). However, these methods could only use plain text, not other clipboard data like images. My version of Python is 3.x on Windows but the answer needs to be cross-platform (work on different operating systems) and should also support other Python versions like 2.x. I

INTRODUCTION AND RELEVANT INFORMATION: I have an edit control that needs to accept only signed decimal numbers ( something like -12.35 ). I have decided to implement this via subclassing . The WM_CHAR handler seems to works well, and I need to handle several other messages to completely protect user from entering invalid text. One such message is WM_PASTE . So far I was able to properly get the text from the clipboard and to discard or pass the message depending if the copied string is indeed decimal number. Edit control has limited input to 12 characters. This is done via EM_SETLIMITTEXT

CanIUse.com shows that all major browsers have at least partial Clipboard API support while FF has full support: https://caniuse.com/#feat=clipboard However, I cannot find any tutorials or simple examples of how to write to the clipboard using HTML5 (no flash). Does anyone know what exactly partial support means, is this feature usable? If it only worked in Chrome/FF that would be sufficient for my needs. I recently did an intense research on the W3C Clipboard API (which is up to this writing still in the working draft stage) support in the following browsers (latest versions): Internet

I'm using Dart to develop a personal whiteboard Chrome app and it is sometimes useful to be able to quickly copy and paste an image (e.g. a slide from a presentation, a diagram or a handout) so that I can add notes over the image while teaching a class or giving a presentation. How can I paste an image stored on the clipboard onto a canvas element in Dart? Richard Ambler Actually, this answer to the same question for JS is almost directly applicable. A Dart translation might look something like: import 'dart:html'; void main() { var can = new CanvasElement() ..width = 600 ..height = 600 ; var

I'm workin on a multi-thread application and I face the issue of having to use the clipboard (I'm working with the Qlikview API - and I need to copy tables into excel) and the problem is that I think what will happen is something like this: On thread#1 I open the QW document and copy the table, and before I get to paste it in the excel sheet, thread#2 comes along and uses the clipboard to copy table from its document. I'm curious whether it is even possible to use the clipboard from a multithreading application? I've read all sorts of things about using the clipboard and the only clear thing

I know this command will paste the clipboard contents into a file: xclip -out -selection clipboard >> file.txt If I want to paste clipboard content into a variable like a string what do I do? To assign the output of a command to a variable, you can use command substitution: myvar=$( command ) echo "$myvar" 来源： https://stackoverflow.com/questions/23046580/paste-clipboard-content-into-a-variable-in-bash-using-xclip
