What porting means
● Before Fremantle:● Make an application RUN in Maemo
● After Fremantle:● ADAPT an application to Maemo
Page 5

Why bothering?
● Your application gets better● Your users get happier● Your fingers too!

GNOME Applications
● Coding will be easier – it is GTK+!● Lots of interesting applications waiting to be ported!● If you're a GNOME user, you may have your common
applications available to you.

Root view / sub view philosophy
● Applications are stacks of windows
● The root window is the base● E.g.: List of emails
● Actions that break the usage flow, will be sub views:● E.g.: Reading an email

This means: no GTKPaned!

When a box is tapped,a dialog appears...
Page 19
Use a GtkToggle button or a HildonPickerButton
Page 20
Replaced the GtkSpinButtons by HildonEntries and not by HildonPickerButtons because the changes are shown immediately in the image.
Assign the numeric GtkInputMode
Page 21
Text is the focus here, so, instead of a GtkNotebook, the style properties are in a GtkDialog launched from the text properties HildonAppMenu
Page 22
GtkSpinButtons are replaced by HildonPickerButtons with a TouchSelectorEntry assigned

HildonAppMenu
● Really different from a GtkMenu!!
● Do not stuff it: Keep a low number of items
● Use filters to display HOW contents are shown, not WHICH contents are shown

DRY: Don't Repeat Yourself
How to keep a low number of menu items?
Page 26
Choose the most used/important menus and sub-menus from the menu bar.
Pages can be chosen using gestures, so, no need for Next/Previous menus.
Page 27
The status bar and toolbar are not used in EOG for Maemo, so, no menus are needed.
The Zoom In / Zoom Out functionalities are accomplished by using the Increase / Decrease hard-keys.

Following the Hildon Interface Guidelines
● HIG says: don't show menu items that are insensitive● Here's a helpful tip:
● Connect a callback to the “show” signal of each HildonAppMenu item
● The callback shows/hides the item according to its “sensitive” property

Preferences Dialogs
● Dialogs with a GtkNotebook to group different kinds of preferences
● Tabs' labels define groups' names
Page 32
Adapting GNOME Applications to Maemo Fremantle · Joaquim Rocha <[email protected] >
How to migrate it to Fremantle?
● Use a HildonPannableArea
● Add a GtkVBox with ALL the preferences groups and use a GtkLabel above each one, identifying it
