Each screens has two parts: +- a Glade file with the UI elements +- a Python script with functionality + +The Glade files are stored in the ui/ directory, the Python scripts - in ui/. +The actual names of files are irrelevant, but it's useful to follow the +convention - call the Glade file screenname.glade, the Python script - +screenname_gui.py. + +Your Glade interface should be inside a containter. You will need the name of +this containter in order to load it with your Python script. + +The Python script is mostly free-form, but there are certain things that you +need to do. + +First of all, import all the modules that you want to use. You will NEED to +import gtk and gtk.glade, otherwise you won't be able to load your UI. + +Create a class, it's good to follow the convention call the class +ScreennameWindow. It has to accept InstallWindow as the only argument. + +You're free to do anything you want inside the class, but the dispatcher +assumes you have two functions - getNext(self) and getScreen(self, anaconda). +The second parameter of getScreen is the anaconda object with all the settings +etc that you might want. + +getNext should return None, and getScreen should return None if you want to, +for any reason, skip the screen (perhaps it is a special screen that handles +some odd case and is otherwise unneeded), or the container box that will be +displayed inside the screen. + +Before the screen is shown, getScreen is called. This is the place to create +any default settings and store whatever you'll need in getNexn. The container +it returns will be displayed on the screen (so it is actually possible to +create screens without a Glade file). + +When the "Next" button is clicked by the user, getNext is called. This is the +place to store all the settings that you want in the anaconda object. While it +is technically possible to run whatever code, it is recommended that you store +the information that you'll need in anaconda, and run the code later, when the +system is installing (there are some exceptions, just use common sense). + +When your screen is finished, you'll need to add it in three places: +- the dispatcher (dispatch.py) +- the install class (installclass.py) +- the GUI (gui.py). + +All three parts need to know about your script in order for it to be +displayed. + +In dispatch.py, find installSteps and add your screen. The dispatcher is a +simple state machine that goes through all the screens and displays them in +sequence, assuming they are in the install class and in the GUI. +The syntax is ( name, Function ) where the name is the screenname, and the +Function can be empty or a function *in the dispatcher* that you want to be +called instead of Screenname.getScreen. + +In gui.py, add your screen to stepToClass. The syntax is +name: (screen_file, screen_class), where name is the same name that you put in +the dispatcher, the screen_file is the Python script for your screen without +extension ("screenname_gui"), and screen_class is the class in your script +("ScreennameWindow"). + +In installclass.py, add the name of the screen (the same as you've used for +the previous two files) to dispatch.setStepList in setSteps. + +Now, you need to tell the installer to perform some actions based on the +settings the user has entered. You can do this in the gentoo/livecd.py file. +Find the doPreInstall/doInstall/doPostInstall/writeConfiguration functions (as +appropriate, depending on when you want your actions to run) and simply +program in what you want. It's a good idea to create a separate function for +each action to keep the procedures clean - the best place for such functions +is the gentoo/utils.py file. Add your function to the GentooInstall class in +the gentoo/utils.py file and it will be available in gentoo/livecd.py through +self._gentoo_install (it's an instance of the GentooInstall class from +gentoo/utils.py). + +That's it ;-) + +Here's a simple Python template: + +import gtk +import gtk.glade + +class TemplateWindow(InstallWindow): + def getNext(self): + # Save your settings to self.anaconda + return None + + def getScreen(self, anaconda): + self.anaconda = anaconda + (self.xml, self.container) = gui.getGladeWidget("sample.glade", + "sample_box") + # your widgets will now be available through + # self.xml.getWidget(widget_name) - keep the xml in self as + # you'll most likely need it in getNext. + return self.containter + + diff --git a/docs/files.txt b/docs/files.txt new file mode 100644 index 0000000..57e3c74 --- /dev/null +++ b/docs/files.txt @@ -0,0 +1,44 @@ + ****************************** + * Gentoo Anaconda port * + ****************************** + + Description of the tree + by wiktor w brodlo <wiktor@brodlo.net> + +Below is a description of every directory and the more important files in the +source tree. + +/ The files in the main directory are various helpers, and +| scripts that implement top-level functionality. ++-anaconda This python file is the core Anaconda.

When you're ready, reboot, remove the LiveDVD from the drive and let +your new Gentoo boot. Enjoy! ;-) |
