Hildon-Extras

Hildon-Extras is a set of community-contributed widgets (that's GTK+ widgets, not Desktop widgets) and dialogs that can be used by application developers to provide a usable, well-balanced interface. Some of these widgets provide functionality that the "stock" Hildon widgets don't provide, and some dialogs are touch-friendly versions of existing dialogs in GTK+ and/or Hildon.

Current status

Hildon-Extras is very close to being released. The components are considered quite stable, but some small polishing is needed until release.

Qt integration

There is a class called QtHeWrapper in Hildon-Extras that is provided to developers of Qt-based apps. It is a wrapper that provides interoperability between Hildon-Extras and Qt code. It allows developers to call Hildon-Extras easily from Qt-based software.

The QtHeWrapper currenty supports all the dialogs in Hildon-Extras. It allows for easily displaying any of the dialogs.

Dialogs

Hildon-Extras has a nice collection of dialog windows that are optimized to be both good-looking and finger-friendly.

All of the dialogs support integration with Qt-based software via the QtHeWrapper class (in the "qt-he-wrapper.h" header).

HeAboutDialog

About dialog in MaePad

The HeAboutDialog is a replacement for GtkAboutDialog and provides a finger-friendly, good-looking about dialog with optional buttons for:

  • Project website
  • Bug tracker ("Enter new bug")
  • Donations page

There is a wrapper that can be used by Qt-based applications for this dialog in QtHeWrapper.

HeSimpleColorDialog

Simple color dialog

This dialog provides a finger-friendly, limited list of colors (a Tango-ish color palette) for the user to choose from. Especially useful when the color selection does not have to be "that special shade of green" but rather "a nice green" (for example to colorize categories or items).

There is also the possibility of an advanced mode for this dialog. This presents an additional "Advanced" button above "Select". When clicked, it presents the user with a regular HeColorDialog to pick an exact colour.

Example code and use cases:

  • MaePad uses it for coloring the text of checklist items and for the color in sketches (src/ui/callbacks.c)

HeColorDialog

Color dialog

This dialog lets the user to select a color by selecting the intensity of the red, green, and blue channels. Also provides hex input/output of colours.

It may come in handy when a developer wants his/her users to be able to pick an exact shade of an exact colour in a finger-friendly way.

HeFontDialog

Font dialog

Lets the user choose a font together with a font size. It also offers bold and italic styles.


Buttons

The buttons in Hildon-Extras provide commonly used behaviour and are looking nice.

HeCheckButton

Check button

HeCheckButton is a check button with primary and secondary labels. The standard HildonCheckButton supports only one label.

This button can be very handy for developers who would like to provide some description about the functionality of a check box.

HeFullscreenButton

The HeFullScreenButton

HeFullscreenButton is a button that allows users to leave full screen mode. It becomes visible after the user touched the screen or pressed a key and it vanishes after 5 seconds of inactivity.

It looks like the full screen button in the built-in applications of Maemo 5, so it is very good if a developer wants his/her application to blend in well with the rest of the platform.

HeColorButton

Color button

On tapping the HeColorButton opens the HeColorDialog and lets the user select a color. This color is then displayed on the HeColorButton.

HeFontButton

Font button

On tapping the HeFontButton displays a HeFontDialog that lets the user select a font. The selected font is then displayed on the HeFontButton.
