* @Short_description: A widget displaying an image
|

* @Title: GtkImage
|

|
|
|
* @See_also:#GdkPixbuf
|
|
|
|
|
*
|
|
|
|
|
* The #GtkImage widget displays an image. Various kinds of object
|
|
|
|
|
* can be displayed as an image; most typically, you would load a
|
|
|
|
|
* #GdkPixbuf ("pixel buffer") from a file, and then display that.
|
2014-02-07 18:01:26 +00:00
|
|
|
|
* There’s a convenience function to do this, gtk_image_new_from_file(),
|
2009-12-18 00:59:21 +00:00
|
|
|
|
* used as follows:
|

|
|
|

|
|
|
|
|
* image = gtk_image_new_from_file ("myfile.png");
|

|
|
|
|
* ]|
|
2014-02-07 18:32:47 +00:00
|
|
|
|
* If the file isn’t loaded successfully, the image will contain a
|
2014-02-05 18:07:34 +00:00
|
|
|
|
* “broken image” icon similar to that used in many web browsers.
|
2009-12-18 00:59:21 +00:00
|
|
|
|
* If you want to handle errors in loading the file yourself,
|
|
|
|
|
* for example by displaying an error message, then load the image with
|
|
|
|
|
* gdk_pixbuf_new_from_file(), then create the #GtkImage with
|
|
|
|
|
* gtk_image_new_from_pixbuf().
|
|
|
|
|
*
|
|
|
|
|
* The image file may contain an animation, if so the #GtkImage will
|
|
|
|
|
* display an animation (#GdkPixbufAnimation) instead of a static image.
|
|
|
|
|
*
|
2014-02-05 18:07:34 +00:00
|
|
|
|
* #GtkImage is a “no window” widget (has no #GdkWindow of its own),
|
2009-12-18 00:59:21 +00:00
|
|
|
|
* so by default does not receive events. If you want to receive events
|
|
|
|
|
* on the image, such as button clicks, place the image inside a
|
|
|
|
|
* #GtkEventBox, then connect to the event signals on the event box.

|
|
* allows you to convert an image into a C variable declaration, which

up the icon set for a given stock ID. GTK maintains a stack of
GtkIconFactory to search, and applications or libraries can add
additional icon factories on top of the stack

Move more text widget headers into the private header list
2000-09-26 Havoc Pennington <hp@redhat.com>
* gtk/Makefile.am (gtk_private_h_sources): Move more text widget
headers into the private header list
* Makefile.am (pkgconfig_DATA): install pkg-config files
* configure.in: add pkg-config files
* gdk-2.0.pc.in, gdk-pixbuf.pc.in, gtk+-2.0.pc.in: pkg-config files
* gtk/gtkwindow.c (gtk_window_read_rcfiles): Invalidate
outstanding icon caches on theme change.
* gtk/gtkiconfactory.h, gtk/gtkiconfactory.c: New icon system. Three
important types:
(GtkIconSource): Specification for creating a pixbuf
appropriate for a direction/state/size triplet from
a source pixbuf or filename
(GtkIconSet): List of GtkIconSource objects that are used to
create the "same" icon (e.g. an OK button icon), and cache for
rendered icons
(GtkIconFactory): Hash from stock ID to GtkIconSet; used to look
up the icon set for a given stock ID. GTK maintains a stack of
GtkIconFactory to search, and applications or libraries can add
additional icon factories on top of the stack
* gtk/gtkrc.h, gtk/gtkrc.c: When loading an RcStyle, parse
the set of GtkIconSource specified for a given stock ID into
a GtkIconSet, and put the GtkIconSet into a GtkIconFactory for the
RcStyle, under the specified stock ID.
* gtk/gtkstyle.h, gtk/gtkstyle.c: Add a virtual function
render_icon used to derive a GdkPixbuf from a GtkIconSource.
This allows people to theme how prelight, insensitive, etc. are
done.
(gtk_style_lookup_icon_set): Look up a stock ID in the list of
icon factories for a style, and return the resulting
icon set if any.
(gtk_style_render_icon): Render an icon using the render_icon
method in the GtkStyleClass.
* gtk/gtkwidget.h, gtk/gtkwidget.c (gtk_widget_render_icon):
Use the style for a given widget to look up a stock ID, get the
icon set, and render an icon using the render_icon method
of the style
* gtk/gtkstock.h, gtk/gtkstock.c: Header with the GtkStockItem type
(contains information about a stock item), the built-in stock item
IDs, and functions to add/lookup stock items.
* gtk/stock-icons/*: Stock icons that come with GTK
* gtk/gtkbutton.h, gtk/gtkbutton.c (gtk_button_new_stock): Returns
a button based on a GtkStockItem
(gtk_button_new_accel): Takes a uline string and accel group, and
installs the accelerator.
* gtk/gtkimage.h, gtk/gtkimage.c: Make this into a generic
image-display widget.

up the icon set for a given stock ID. GTK maintains a stack of
GtkIconFactory to search, and applications or libraries can add
additional icon factories on top of the stack

Move more text widget headers into the private header list
2000-09-26 Havoc Pennington <hp@redhat.com>
* gtk/Makefile.am (gtk_private_h_sources): Move more text widget
headers into the private header list
* Makefile.am (pkgconfig_DATA): install pkg-config files
* configure.in: add pkg-config files
* gdk-2.0.pc.in, gdk-pixbuf.pc.in, gtk+-2.0.pc.in: pkg-config files
* gtk/gtkwindow.c (gtk_window_read_rcfiles): Invalidate
outstanding icon caches on theme change.
* gtk/gtkiconfactory.h, gtk/gtkiconfactory.c: New icon system. Three
important types:
(GtkIconSource): Specification for creating a pixbuf
appropriate for a direction/state/size triplet from
a source pixbuf or filename
(GtkIconSet): List of GtkIconSource objects that are used to
create the "same" icon (e.g. an OK button icon), and cache for
rendered icons
(GtkIconFactory): Hash from stock ID to GtkIconSet; used to look
up the icon set for a given stock ID. GTK maintains a stack of
GtkIconFactory to search, and applications or libraries can add
additional icon factories on top of the stack
* gtk/gtkrc.h, gtk/gtkrc.c: When loading an RcStyle, parse
the set of GtkIconSource specified for a given stock ID into
a GtkIconSet, and put the GtkIconSet into a GtkIconFactory for the
RcStyle, under the specified stock ID.
* gtk/gtkstyle.h, gtk/gtkstyle.c: Add a virtual function
render_icon used to derive a GdkPixbuf from a GtkIconSource.
This allows people to theme how prelight, insensitive, etc. are
done.
(gtk_style_lookup_icon_set): Look up a stock ID in the list of
icon factories for a style, and return the resulting
icon set if any.
(gtk_style_render_icon): Render an icon using the render_icon
method in the GtkStyleClass.
* gtk/gtkwidget.h, gtk/gtkwidget.c (gtk_widget_render_icon):
Use the style for a given widget to look up a stock ID, get the
icon set, and render an icon using the render_icon method
of the style
* gtk/gtkstock.h, gtk/gtkstock.c: Header with the GtkStockItem type
(contains information about a stock item), the built-in stock item
IDs, and functions to add/lookup stock items.
* gtk/stock-icons/*: Stock icons that come with GTK
* gtk/gtkbutton.h, gtk/gtkbutton.c (gtk_button_new_stock): Returns
a button based on a GtkStockItem
(gtk_button_new_accel): Takes a uline string and accel group, and
installs the accelerator.
* gtk/gtkimage.h, gtk/gtkimage.c: Make this into a generic
image-display widget.

Move more text widget headers into the private header list
2000-09-26 Havoc Pennington <hp@redhat.com>
* gtk/Makefile.am (gtk_private_h_sources): Move more text widget
headers into the private header list
* Makefile.am (pkgconfig_DATA): install pkg-config files
* configure.in: add pkg-config files
* gdk-2.0.pc.in, gdk-pixbuf.pc.in, gtk+-2.0.pc.in: pkg-config files
* gtk/gtkwindow.c (gtk_window_read_rcfiles): Invalidate
outstanding icon caches on theme change.
* gtk/gtkiconfactory.h, gtk/gtkiconfactory.c: New icon system. Three
important types:
(GtkIconSource): Specification for creating a pixbuf
appropriate for a direction/state/size triplet from
a source pixbuf or filename
(GtkIconSet): List of GtkIconSource objects that are used to
create the "same" icon (e.g. an OK button icon), and cache for
rendered icons
(GtkIconFactory): Hash from stock ID to GtkIconSet; used to look
up the icon set for a given stock ID. GTK maintains a stack of
GtkIconFactory to search, and applications or libraries can add
additional icon factories on top of the stack
* gtk/gtkrc.h, gtk/gtkrc.c: When loading an RcStyle, parse
the set of GtkIconSource specified for a given stock ID into
a GtkIconSet, and put the GtkIconSet into a GtkIconFactory for the
RcStyle, under the specified stock ID.
* gtk/gtkstyle.h, gtk/gtkstyle.c: Add a virtual function
render_icon used to derive a GdkPixbuf from a GtkIconSource.
This allows people to theme how prelight, insensitive, etc. are
done.
(gtk_style_lookup_icon_set): Look up a stock ID in the list of
icon factories for a style, and return the resulting
icon set if any.
(gtk_style_render_icon): Render an icon using the render_icon
method in the GtkStyleClass.
* gtk/gtkwidget.h, gtk/gtkwidget.c (gtk_widget_render_icon):
Use the style for a given widget to look up a stock ID, get the
icon set, and render an icon using the render_icon method
of the style
* gtk/gtkstock.h, gtk/gtkstock.c: Header with the GtkStockItem type
(contains information about a stock item), the built-in stock item
IDs, and functions to add/lookup stock items.
* gtk/stock-icons/*: Stock icons that come with GTK
* gtk/gtkbutton.h, gtk/gtkbutton.c (gtk_button_new_stock): Returns
a button based on a GtkStockItem
(gtk_button_new_accel): Takes a uline string and accel group, and
installs the accelerator.
* gtk/gtkimage.h, gtk/gtkimage.c: Make this into a generic
image-display widget.

Move more text widget headers into the private header list
2000-09-26 Havoc Pennington <hp@redhat.com>
* gtk/Makefile.am (gtk_private_h_sources): Move more text widget
headers into the private header list
* Makefile.am (pkgconfig_DATA): install pkg-config files
* configure.in: add pkg-config files
* gdk-2.0.pc.in, gdk-pixbuf.pc.in, gtk+-2.0.pc.in: pkg-config files
* gtk/gtkwindow.c (gtk_window_read_rcfiles): Invalidate
outstanding icon caches on theme change.
* gtk/gtkiconfactory.h, gtk/gtkiconfactory.c: New icon system. Three
important types:
(GtkIconSource): Specification for creating a pixbuf
appropriate for a direction/state/size triplet from
a source pixbuf or filename
(GtkIconSet): List of GtkIconSource objects that are used to
create the "same" icon (e.g. an OK button icon), and cache for
rendered icons
(GtkIconFactory): Hash from stock ID to GtkIconSet; used to look
up the icon set for a given stock ID. GTK maintains a stack of
GtkIconFactory to search, and applications or libraries can add
additional icon factories on top of the stack
* gtk/gtkrc.h, gtk/gtkrc.c: When loading an RcStyle, parse
the set of GtkIconSource specified for a given stock ID into
a GtkIconSet, and put the GtkIconSet into a GtkIconFactory for the
RcStyle, under the specified stock ID.
* gtk/gtkstyle.h, gtk/gtkstyle.c: Add a virtual function
render_icon used to derive a GdkPixbuf from a GtkIconSource.
This allows people to theme how prelight, insensitive, etc. are
done.
(gtk_style_lookup_icon_set): Look up a stock ID in the list of
icon factories for a style, and return the resulting
icon set if any.
(gtk_style_render_icon): Render an icon using the render_icon
method in the GtkStyleClass.
* gtk/gtkwidget.h, gtk/gtkwidget.c (gtk_widget_render_icon):
Use the style for a given widget to look up a stock ID, get the
icon set, and render an icon using the render_icon method
of the style
* gtk/gtkstock.h, gtk/gtkstock.c: Header with the GtkStockItem type
(contains information about a stock item), the built-in stock item
IDs, and functions to add/lookup stock items.
* gtk/stock-icons/*: Stock icons that come with GTK
* gtk/gtkbutton.h, gtk/gtkbutton.c (gtk_button_new_stock): Returns
a button based on a GtkStockItem
(gtk_button_new_accel): Takes a uline string and accel group, and
installs the accelerator.
* gtk/gtkimage.h, gtk/gtkimage.c: Make this into a generic
image-display widget.
