Ubuntu Quickly: How do I set a button to launch a specific Ubuntu Application

rated 0 times [ 0] [ 0] / answers: 1 / hits: 993 / 3 Years ago, fri, october 8, 2021, 2:10:25

I'm very new to linux and I don't know very much. I was creating my own application with Quickly, and I wanted to have a button which launches the Hardware Information application "Hardinfo". I'm very new and I literally don't know anything, any help would be very much appreciated. Thanks in advance!

Update: I'm not looking for a keyboard shortcut, by button I meant a gtk-button inside glade. How to I set it so that when clicked it would take me to the application "hardinfo". If this isn't possible, then how can I set the button to emulate a keyboard shortcut once clicked, inside glade, Thankssssss!

Update 2: What I'm looking for is a step by step process of how to do this from someone who knows glade and quickly completely, because I have no idea how the codes work and where I'm supposed to put them :/

OK, how about a clear and concise (working) example:

quickly create ubuntu-application test

cd test

quickly design

Add a button somewhere with Glade (by default it is called "button1")

Save and close Glade

quickly edit and go to TestWindow.py

Add the following at the top of the file:

from multiprocessing import Process

import subprocess

Add the following to the end of the file and make sure it is indented properly (pro tip: select the block of text in Gedit and hit tab to indent the whole block):
```
def on_button1_clicked(self, widget, data=None):

    p = Process(target=self.launch_hardinfo)

    p.start()



def launch_hardinfo(self):

    subprocess.call(["hardinfo"])
```
These two functions work together. Process.start() calls TestWindow.launch_hardinfo (that's the target= parameter to the Process constructor) in a new thread so that subprocess.call() doesn't block the application.

Save TestWindow.py

quickly run and and click the button.

I had a little issue because I was trying to assign signals in Glade, but you don't even need to do that. The Quickly library actually allows you to do stuff like on_button1_click() which means "when the control called button1 is clicked." Simple as that! Hopefully this should get you started.
