new

iconSourceNew

Arguments

:: (HasCallStack, MonadIO m)

=> m IconSource

Returns: a new IconSource

Deprecated: (Since version 3.10)Use IconTheme instead.

Creates a new IconSource. A IconSource contains a Pixbuf (or image filename) that serves as the base image for one or more of the icons in a IconSet, along with a specification for which icons in the icon set will be based on that pixbuf or image file. An icon set contains a set of icons that represent “the same” logical concept in different states, different global text directions, and different sizes.

So for example a web browser’s “Back to Previous Page” icon might point in a different direction in Hebrew and in English; it might look different when insensitive; and it might change size depending on toolbar mode (small/large icons). So a single icon set would contain all those variants of the icon. IconSet contains a list of IconSource from which it can derive specific icon variants in the set.

In the simplest case, IconSet contains one source pixbuf from which it derives all variants. The convenience function iconSetNewFromPixbuf handles this case; if you only have one source pixbuf, just use that function.

If you want to use a different base pixbuf for different icon variants, you create multiple icon sources, mark which variants they’ll be used to create, and add them to the icon set with iconSetAddSource.

By default, the icon source has all parameters wildcarded. That is, the icon source will be used as the base icon for any desired text direction, widget state, or icon size.

setDirection

iconSourceSetDirection

Arguments

:: (HasCallStack, MonadIO m)

=> IconSource

source: a IconSource

-> TextDirection

direction: text direction this source applies to

-> m ()

Deprecated: (Since version 3.10)Use IconTheme instead.

Sets the text direction this icon source is intended to be used with.

Setting the text direction on an icon source makes no difference if the text direction is wildcarded. Therefore, you should usually call iconSourceSetDirectionWildcarded to un-wildcard it in addition to calling this function.

setDirectionWildcarded

iconSourceSetDirectionWildcarded

Arguments

:: (HasCallStack, MonadIO m)

=> IconSource

source: a IconSource

-> Bool

setting: True to wildcard the text direction

-> m ()

Deprecated: (Since version 3.10)Use IconTheme instead.

If the text direction is wildcarded, this source can be used as the base image for an icon in any TextDirection. If the text direction is not wildcarded, then the text direction the icon source applies to should be set with iconSourceSetDirection, and the icon source will only be used with that text direction.

IconSet prefers non-wildcarded sources (exact matches) over wildcarded sources, and will use an exact match when possible.

setFilename

iconSourceSetFilename

Arguments

:: (HasCallStack, MonadIO m)

=> IconSource

source: a IconSource

-> [Char]

filename: image file to use

-> m ()

Deprecated: (Since version 3.10)Use IconTheme instead.

Sets the name of an image file to use as a base image when creating icon variants for IconSet. The filename must be absolute.

setIconName

iconSourceSetIconName

Arguments

:: (HasCallStack, MonadIO m)

=> IconSource

source: a IconSource

-> Maybe Text

iconName: name of icon to use

-> m ()

Deprecated: (Since version 3.10)Use IconTheme instead.

Sets the name of an icon to look up in the current icon theme to use as a base image when creating icon variants for IconSet.

setPixbuf

iconSourceSetPixbuf

Arguments

:: (HasCallStack, MonadIO m, IsPixbuf a)

=> IconSource

source: a IconSource

-> a

pixbuf: pixbuf to use as a source

-> m ()

Deprecated: (Since version 3.10)Use IconTheme instead.

Sets a pixbuf to use as a base image when creating icon variants for IconSet.

setSize

iconSourceSetSize

Arguments

:: (HasCallStack, MonadIO m)

=> IconSource

source: a IconSource

-> Int32

size: icon size (tIconSize) this source applies to

-> m ()

Deprecated: (Since version 3.10)Use IconTheme instead.

Sets the icon size this icon source is intended to be used with.

Setting the icon size on an icon source makes no difference if the size is wildcarded. Therefore, you should usually call iconSourceSetSizeWildcarded to un-wildcard it in addition to calling this function.

setSizeWildcarded

iconSourceSetSizeWildcarded

Arguments

:: (HasCallStack, MonadIO m)

=> IconSource

source: a IconSource

-> Bool

setting: True to wildcard the widget state

-> m ()

Deprecated: (Since version 3.10)Use IconTheme instead.

If the icon size is wildcarded, this source can be used as the base image for an icon of any size. If the size is not wildcarded, then the size the source applies to should be set with iconSourceSetSize and the icon source will only be used with that specific size.

IconSet prefers non-wildcarded sources (exact matches) over wildcarded sources, and will use an exact match when possible.

IconSet will normally scale wildcarded source images to produce an appropriate icon at a given size, but will not change the size of source images that match exactly.

setState

iconSourceSetState

Arguments

:: (HasCallStack, MonadIO m)

=> IconSource

source: a IconSource

-> StateType

state: widget state this source applies to

-> m ()

Deprecated: (Since version 3.10)Use IconTheme instead.

Sets the widget state this icon source is intended to be used with.

Setting the widget state on an icon source makes no difference if the state is wildcarded. Therefore, you should usually call iconSourceSetStateWildcarded to un-wildcard it in addition to calling this function.

setStateWildcarded

iconSourceSetStateWildcarded

Arguments

:: (HasCallStack, MonadIO m)

=> IconSource

source: a IconSource

-> Bool

setting: True to wildcard the widget state

-> m ()

Deprecated: (Since version 3.10)Use IconTheme instead.

If the widget state is wildcarded, this source can be used as the base image for an icon in any StateType. If the widget state is not wildcarded, then the state the source applies to should be set with iconSourceSetState and the icon source will only be used with that specific state.

IconSet prefers non-wildcarded sources (exact matches) over wildcarded sources, and will use an exact match when possible.

IconSet will normally transform wildcarded source images to produce an appropriate icon for a given state, for example lightening an image on prelight, but will not modify source images that match exactly.
