# How to update a Deluge 1.3 plugin for 2.0
|
|
|
|
|
|
|
|
With the new code in Deluge 2.0 there are changes that require authors of
|
|
|
|
existing plugins to update their plugins to work on Deluge 2.0.
|
|
|
|
|
|
|
|
The main changes are with Python 3 support and the new GTK3 user interface with
|
|
|
|
the dropping of GTK2. However it is still possible for a 1.3 plugin to be made
|
|
|
|
compatible with 2.0 and this guide aims to helps with that process.
|
|
|
|
|
|
|
|
## Python
|
|
|
|
|
|
|
|
### Python version matching
|
|
|
|
|
2021-12-28 20:20:57 +00:00
|
|
|
Ensure your code is Python >=3.6 compatible.

|
|
|
In `1.3-stable` the plugins that were built with a specific version of Python
|
|
|
|
would only be loaded if the system Python also matched.
|
2018-11-01 18:34:52 +00:00
|
|
|
|
|
|
|
This has change in Deluge 2.0 and it will load any Python version of plugin
|
|
|
|
eggs so compatibility is essential for end-users not to encounter issues.
|
|
|
|
|
|
|
|
## GTK 3 addition
|
|
|
|
|
|
|
|
In order to support both Deluge 1.3 and 2.0 all existing plugin GTK UI files
|
|
|
|
must be copied and then converted to contain only GTK3 code with the old files
|
|
|
|
still using PyGTK e.g.:
|
|
|
|
|
|
|
|
cp gtkui.py gtk3ui.py
|
|
|
|
|
|
|
|
### Convert from libglade to GtkBuilder
|
|
|
|
|
|
|
|
With PyGTK there were two library options for creating the user interface from
|
|
|
|
XML files by default Deluge plugins used libglade but that has been deprecated
|
|
|
|
and removed in GTK3. So the libglade `.glade` files will need converted to
|
|
|
|
GtkBuilder `.ui` files and the Python code updated.
|
|
|
|

|
|
See the official [Migrating to GtkBuilder][migrate-gtkbuilder] document for more details.

|
|
#### GtkBuilder conversion script
|
2018-11-01 18:34:52 +00:00
|
|
|
|
|
|
|
Install the `gtk-builder-convert` converter on Ubuntu with:
|
|
|
|
|
|
|
|
sudo apt install libgtk2.0-dev
|
|
|
|
|
|
|
|
To convert your GTK run it like so:
|
|
|
|
|
|
|
|
gtk-builder-convert data/config.glade data/config.ui
|
|
|
|
|
|
|
|
#### Glade UI designer for GTK2
|
|
|
|
|
2019-06-15 10:49:07 +00:00
|
|
|
The above conversion can also be done in Glade UI designer (version <=3.8).
|
|
|
|
|
|
|
|
In the preferences select `GtkBuilder` as the project file format. Ensure
|
|
|
|
that the minimum Gtk version is set to 2.24 and fix any deprecated widgets.
|
|
|
|
|
|
|
|
The updated file should be saved with file extension `.ui`.
|

|
|
|
|
|
|
|
#### Python code changes
|
|
|
|
|
|
|
|
The code needs to replace `gtk.glade` references with `gtk.Builder` and the
|
|
|
|
first step is updating how the files are loaded:
|
|
|
|
|
|
|
|
```diff
|
2019-06-15 10:49:07 +00:00
|
|
|
- glade = gtk.glade.XML(get_resource("config.glade"))
|
|
|
|
+ builder = Gtk.Builder.new_from_file(get_resource("config.ui"))
|
2018-11-01 18:34:52 +00:00
|
|
|
```
|
|
|
|
|
2019-06-15 10:49:07 +00:00
|
|
|
Replace signals method:
|
|
|
|
|
|
|
|
```diff
|
|
|
|
- glade.signal_autoconnect(self)
|
|
|
|
+ builder.connect_signals(self)
|
|
|
|
```
|
|
|
|
|
|
|
|
Replace `get_widget` with `get_object`:
|
|
|
|
|
|
|
|
```diff
|
|
|
|
- glade.get_widget
|
|
|
|
+ builder.get_object
|
|
|
|
```
|
2018-11-01 18:34:52 +00:00
|
|
|
|
2019-06-15 10:49:07 +00:00
|
|
|
Check for any remaining `glade` methods and replace with the `builder` equivalents.
|

|
|
|
|
|
|
|
### Migrate XML files to GTK3
|
|
|
|
|
|
|
|
If you open and save the file it will update with the new requirement header:
|
|
|
|
|
|
|
|
<!-- Generated with glade 3.18.3 -->
|
|
|
|
<interface>
|
2019-06-15 10:49:07 +00:00
|
|
|
<requires lib="gtk+" version="3.10"/>
|
2018-11-01 18:34:52 +00:00
|
|
|
|
|
|
|
You can fix deprecated widgets but keep the minimum GTK version to <= 3.10 for
|
2019-06-15 18:44:33 +00:00
|
|
|
desktop compatibility.

### Gtk import rename
|
|
|
|
|
|
|
|
Move from PyGTK to GTK3 using Python bindings.

|
|
|
|
+ self.builder = Gtk.Builder()

### Deluge GTK3
|

|
|
|
#### Imports
|
2018-11-01 18:34:52 +00:00
|
|
|
|
2019-06-15 10:49:07 +00:00
|
|
|
Imports will need renamed from `deluge.ui.gtkui` to `deluge.ui.gtk3`.
|
|
|
|
|
|
|
|
There is also a new PluginBase for Gtk3 UI:
|
2018-11-01 18:34:52 +00:00
|
|
|
|
|
|
|
```diff
|
|
|
|
-from deluge.plugins.pluginbase import GtkPluginBase
|
|
|
|
+from deluge.plugins.pluginbase import Gtk3PluginBase
|
|
|
|
-class GtkUI(GtkPluginBase):
|
|
|
|
+class Gtk3UI(Gtk3PluginBase):
|
|
|
|
```
|
|
|
|
|
2019-06-15 10:49:07 +00:00
|
|
|
#### Entry points
|
|
|
|
|
|
|
|
To enable the GTK3 UI to find the plugin the entry points requires updating too.
|
|
|
|
|
|
|
|
In the plugin `__init__.py` file add a new `Gtk3UIPlugin` class:
|
|
|
|
|
|
|
|
```
|
|
|
|
class Gtk3UIPlugin(PluginInitBase):
|
|
|
|
def __init__(self, plugin_name):
|
|
|
|
from .gtk3ui import Gtk3UI as _plugin_cls
|
|
|
|
self._plugin_cls = _plugin_cls
|
|
|
|
super(Gtk3UIPlugin, self).__init__(plugin_name)
|
|
|
|
```
|
|
|
|
|
|
|
|
A new entry for GTK3 UI can then be added to `setup.py`:
|
|
|
|
|
|
|
|
```diff
|
|
|
|
[deluge.plugin.gtkui]
|
|
|
|
%s = %s:GtkUIPlugin
|
|
|
|
+ [deluge.plugin.gtk3ui]
|
|
|
|
+ %s = deluge_%s:Gtk3UIPlugin
|
|
|
|
[deluge.plugin.webui]
|
|
|
|
%s = %s:WebUIPlugin
|
|
|
|
- """ % ((__plugin_name__, __plugin_name__.lower())*3)
|
|
|
|
+ """ % ((__plugin_name__, __plugin_name__.lower())*4)
|
|
|
|
```
