The main screen is shown below. In this case, a new Activity called testgtk2 has been created from the gtk2 "Hello World" template. The left pane shows the files and directories that comprise the Activity and the right pane shows the contents of its main file, activity.py

Create a new Activity

Select the type Gtk2

Name the Activity testgtk2

Start

Press the Run activity button on the toolbar, your testgtk2 Activity will run, it prints Hello World!. (If you look at your Home screen you have a new Activity called testgtk2.)

Stop testgtk2 and return to Develop. Edit line 70 of activity.py, "Hello World!", change this text but be careful only to change the text within the quotation marks. Press the Run activity button, the Activity now displays the new text.

Changing the icon

Shown in the left hand pane is the directory activity with a triangle next to it pointing right. Click on it to see its contents, open activity-helloworld.svg

Line 11 defines the circle of the world in the icon. Change stroke-width to "6.5". You need to restart the laptop to see the changes, the circle is now thicker. Altered-icon.jpg

Changing the version number

The Home view, List view shows the version number of all the installed Activities. The version number discriminates between older and newer versions of an Activity. It is used to tell if you are using the latest version. Sometimes the latest version has a bug and you want to go back to an earlier known good version.

Look in your Home view List view and you will see that testgtk2 is version 1. To alter the version number, edit activity.info line 6 which shows the activity_version=1 , change it to 2.

You may need to restart the laptop to see the changes.

Installing your Activity on another computer

Press the Create bundle button on the home toolbarSave-bundle.jpg, this creates a .xo bundle in the Journal. Copy this to another laptop to install your Activity.
