Hildon provides some helper functions that can be used for commonly performed tasks and functionality blocks. This includes operations on widget styles and probing functions for touch events.
gulong hildon_helper_set_logical_font (GtkWidget *widget,
const gchar *logicalfontname);
This function assigns a defined logical font to the widget and all its child widgets.
it also connects to the "style_set" signal which will retrieve & assign the new font
for the given logical name each time the theme is changed
The returned signal id can be used to disconnect the signal.
When calling multiple times the previous signal (obtained by calling this function) is disconnected
automatically and should not be used.
widget : |
a GtkWidget to assign this logical font for. |
logicalfontname : |
a gchar* with the logical font name to assign to the widget. |
| Returns : | the signal id that is triggered every time theme is changed. 0 if font set failed. |
gulong hildon_helper_set_logical_color (GtkWidget *widget,
GtkRcFlags rcflags,
GtkStateType state,
const gchar *logicalcolorname);
This function assigns a defined logical color to the widget and all it's child widgets.
It also connects to the "style_set" signal which will retrieve & assign the new color
for the given logical name each time the theme is changed.
The returned signal id can be used to disconnect the signal.
When calling multiple times the previous signal (obtained by calling this function) is disconnected
automatically and should not be used.
Example : If the style you want to modify is bg[NORMAL] then set rcflags to GTK_RC_BG and state to GTK_STATE_NORMAL.
widget : |
A GtkWidget to assign this logical font for. |
rcflags : |
GtkRcFlags enumeration defining whether to assign to FG, BG, TEXT or BASE style. |
state : |
GtkStateType indicating to which state to assign the logical color |
logicalcolorname : |
A gchar* with the logical font name to assign to the widget. |
| Returns : | The signal id that is triggered every time theme is changed. 0 if color set failed. |
gboolean hildon_helper_event_button_is_finger
(GdkEventButton *event);
Checks if the given button event is a finger event.
event : |
A GtkEventButton to check |
| Returns : | TRUE if the event is a finger event. |
void hildon_helper_set_insensitive_message
(GtkWidget *widget,
const gchar *message);
hildon_helper_set_insensitive_message is deprecated and should not be used in newly-written code. As of hildon 2.2, it is strongly discouraged to use insensitive messages.
This function assigns an insensitive message to a widget. When the widget is
in an insensitive state and the user activates it, the message will be displayed
using a standard HildonBanner.
widget : |
A GtkWidget to assign a banner to |
message : |
A message to display to the user |
void hildon_helper_set_insensitive_messagef
(GtkWidget *widget,
const gchar *format,
...);
hildon_helper_set_insensitive_messagef is deprecated and should not be used in newly-written code. As of hildon 2.2, it is strongly discouraged to use insensitive messages.
A version of hildon_helper_set_insensitive_message with string formatting.
widget : |
A GtkWidget to assign a banner to |
format : |
a printf-like format string |
... : |
arguments for the format string |
void hildon_helper_set_thumb_scrollbar (GtkScrolledWindow *win,
gboolean thumb);
This function enables a thumb scrollbar on a given scrolled window. It'll convert the existing normal scrollbar into a larger, finger-usable scrollbar that works without a stylus. As fingerable list rows are fairly high, consider using the whole available vertical space of your application for the content in order to have as many rows as possible visible on the screen at once.
Finger-Sized scrollbar should always be used together with finger-sized content.
win : |
A GtkScrolledWindow to use as target |
thumb : |
TRUE to enable the thumb scrollbar, FALSE to disable |
