Description

The Image widget displays an image. Various kinds of object can be displayed as an image; most typically, you would load a Pixbuf ("pixel buffer") from a file, and then display that. There’s a convenience function to do this, imageNewFromFile, used as follows:

C code

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

If the file isn’t loaded successfully, the image will contain a “broken image” icon similar to that used in many web browsers. If you want to handle errors in loading the file yourself, for example by displaying an error message, then load the image with pixbufNewFromFile, then create the Image with imageNewFromPixbuf.

The image file may contain an animation, if so the Image will display an animation (PixbufAnimation) instead of a static image.

Image is a subclass of Misc, which implies that you can align it (center, left, right) and add padding to it, using Misc methods.

Image is a “no window” widget (has no Window of its own), 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 EventBox, then connect to the event signals on the event box.

## Handling button press events on a Image.

C code

 static gboolean
 button_press_callback (GtkWidget      *event_box,
                        GdkEventButton *event,
                        gpointer        data)
 {
   g_print ("Event box clicked at coordinates %f,%f\n",
            event->x, event->y);

   // Returning TRUE means we handled the event, so the signal
   // emission should be stopped (don’t call any further callbacks
   // that may be connected). Return FALSE to continue invoking callbacks.
   return TRUE;
 }

 static GtkWidget*
 create_image (void)
 {
   GtkWidget *image;
   GtkWidget *event_box;

   image = gtk_image_new_from_file ("myfile.png");

   event_box = gtk_event_box_new ();

   gtk_container_add (GTK_CONTAINER (event_box), image);

   g_signal_connect (G_OBJECT (event_box),
                     "button_press_event",
                     G_CALLBACK (button_press_callback),
                     image);

   return image;
 }

When handling events on the event box, keep in mind that coordinates in the image may be different from event box coordinates due to the alignment and padding settings on the image (see Misc). The simplest way to solve this is to set the alignment to 0.0 (left/top), and set the padding to zero. Then the origin of the image will be the same as the origin of the event box.

Sometimes an application will want to avoid depending on external data files, such as image files. GTK+ comes with a program to avoid this, called “gdk-pixbuf-csource”. This library allows you to convert an image into a C variable declaration, which can then be loaded into a Pixbuf using pixbufNewFromInline.

CSS nodes

GtkImage has a single CSS node with the name image.

imageNewFromAnimation Source #

Arguments

:: (HasCallStack, MonadIO m, IsPixbufAnimation a)
=> a	`animation`: an animation
-> m Image	Returns: a new `Image` widget

Creates a Image displaying the given animation. The Image does not assume a reference to the animation; you still need to unref it if you own references. Image will add its own reference rather than adopting yours.

Note that the animation frames are shown using a timeout with PRIORITY_DEFAULT. When using animations to indicate busyness, keep in mind that the animation will only be shown if the main loop is not busy with something that has a higher priority.

newFromFile

imageNewFromFile Source #

Arguments

:: (HasCallStack, MonadIO m)
=> [Char]	`filename`: a filename
-> m Image	Returns: a new `Image`

Creates a new Image displaying the file filename. If the file isn’t found or can’t be loaded, the resulting Image will display a “broken image” icon. This function never returns Nothing, it always returns a valid Image widget.

If the file contains an animation, the image will contain an animation.

If you need to detect failures to load the file, use pixbufNewFromFile to load the file yourself, then create the Image from the pixbuf. (Or for animations, use pixbufAnimationNewFromFile).

The storage type (imageGetStorageType) of the returned image is not defined, it will be whatever is appropriate for displaying the file.

newFromGicon

imageNewFromGicon Source #

Arguments

:: (HasCallStack, MonadIO m, IsIcon a)
=> a	`icon`: an icon
-> Int32	`size`: a stock icon size (`IconSize`)
-> m Image	Returns: a new `Image` displaying the themed icon

Creates a Image displaying an icon from the current icon theme. If the icon name isn’t known, a “broken image” icon will be displayed instead. If the current icon theme is changed, the icon will be updated appropriately.

Since: 2.14

newFromIconName

imageNewFromIconName Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Maybe Text	`iconName`: an icon name or `Nothing`
-> Int32	`size`: a stock icon size (`IconSize`)
-> m Image	Returns: a new `Image` displaying the themed icon

Creates a Image displaying an icon from the current icon theme. If the icon name isn’t known, a “broken image” icon will be displayed instead. If the current icon theme is changed, the icon will be updated appropriately.

Since: 2.6

newFromIconSet

imageNewFromIconSet Source #

Arguments

:: (HasCallStack, MonadIO m)
=> IconSet	`iconSet`: a `IconSet`
-> Int32	`size`: a stock icon size (`IconSize`)
-> m Image	Returns: a new `Image`

Deprecated: (Since version 3.10)Use imageNewFromIconName instead.

Creates a Image displaying an icon set. Sample stock sizes are GTK_ICON_SIZE_MENU, GTK_ICON_SIZE_SMALL_TOOLBAR. Instead of using this function, usually it’s better to create a IconFactory, put your icon sets in the icon factory, add the icon factory to the list of default factories with iconFactoryAddDefault, and then use imageNewFromStock. This will allow themes to override the icon you ship with your application.

The Image does not assume a reference to the icon set; you still need to unref it if you own references. Image will add its own reference rather than adopting yours.

newFromPixbuf

imageNewFromPixbuf Source #

Arguments

:: (HasCallStack, MonadIO m, IsPixbuf a)
=> Maybe a	`pixbuf`: a `Pixbuf`, or `Nothing`
-> m Image	Returns: a new `Image`

Creates a new Image displaying pixbuf. The Image does not assume a reference to the pixbuf; you still need to unref it if you own references. Image will add its own reference rather than adopting yours.

Note that this function just creates an Image from the pixbuf. The Image created will not react to state changes. Should you want that, you should use imageNewFromIconName.

newFromResource

imageNewFromResource Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Text	`resourcePath`: a resource path
-> m Image	Returns: a new `Image`

Creates a new Image displaying the resource file resourcePath. If the file isn’t found or can’t be loaded, the resulting Image will display a “broken image” icon. This function never returns Nothing, it always returns a valid Image widget.

If the file contains an animation, the image will contain an animation.

If you need to detect failures to load the file, use pixbufNewFromFile to load the file yourself, then create the Image from the pixbuf. (Or for animations, use pixbufAnimationNewFromFile).

The storage type (imageGetStorageType) of the returned image is not defined, it will be whatever is appropriate for displaying the file.

Since: 3.4

newFromStock

imageNewFromStock Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Text	`stockId`: a stock icon name
-> Int32	`size`: a stock icon size (`IconSize`)
-> m Image	Returns: a new `Image` displaying the stock icon

Deprecated: (Since version 3.10)Use imageNewFromIconName instead.

Creates a Image displaying a stock icon. Sample stock icon names are STOCK_OPEN, STOCK_QUIT. Sample stock sizes are GTK_ICON_SIZE_MENU, GTK_ICON_SIZE_SMALL_TOOLBAR. If the stock icon name isn’t known, the image will be empty. You can register your own stock icon names, see iconFactoryAddDefault and iconFactoryAdd.

newFromSurface

imageNewFromSurface Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Maybe Surface	`surface`: a `Surface`, or `Nothing`
-> m Image	Returns: a new `Image`

Creates a new Image displaying surface. The Image does not assume a reference to the surface; you still need to unref it if you own references. Image will add its own reference rather than adopting yours.

Since: 3.10

setFromAnimation

No description available in the introspection data.

clearImagePixbufAnimation :: (MonadIO m, IsImage o) => o -> m () Source #

Set the value of the “pixbuf-animation” property to Nothing. When overloading is enabled, this is equivalent to

clear #pixbufAnimation

constructImagePixbufAnimation :: (IsImage o, IsPixbufAnimation a) => a -> IO (GValueConstruct o) Source #

Construct a GValueConstruct with valid value for the “pixbuf-animation” property. This is rarely needed directly, but it is used by new.

getImagePixbufAnimation :: (MonadIO m, IsImage o) => o -> m (Maybe PixbufAnimation) Source #

Get the value of the “pixbuf-animation” property. When overloading is enabled, this is equivalent to

get image #pixbufAnimation

setImagePixbufAnimation :: (MonadIO m, IsImage o, IsPixbufAnimation a) => o -> a -> m () Source #

Set the value of the “pixbuf-animation” property. When overloading is enabled, this is equivalent to

set image [ #pixbufAnimation := value ]

pixelSize

The "pixel-size" property can be used to specify a fixed size overriding the Image:icon-size property for images of type ImageTypeIconName.
