Prima::StdBitmap - shared access to the standard toolkit bitmaps
The toolkit contains sysimage.gif image library, which consists of
a predefined set of images, used in several toolkit modules. To provide
a unified access to the images this module can be used. The images are
assigned a sbmp:: constant, which is used as an index on a load
request. If loaded successfully, images are cached and the successive
requests return the cached values.
The images can be loaded as Prima::Image and Prima::Icon instances.
To discriminate, two methods are used, correspondingly image and icon.
use Prima::StdBitmap; my $logo = Prima::StdBitmap::icon( sbmp::Logo );
Loads INDEXth image frame and returns Prima::Icon instance.
Loads INDEXth image frame and returns Prima::Image instance.
Loads INDEXth image frame from IMAGE_FILE and returns it as either a Prima::Image or
as a Prima::Icon instance, depending on value of boolean AS_ICON flag. If
USE_CACHED_VALUE boolean flag is set, the cached images loaded previously
can be used. If this flag is unset, the cached value is never used, and the
created image is not stored in the cache. Since the module's intended use
is to provide shared and read-only access to the image library, USE_CACHED_VALUE
set to 0 can be used to return non-shared images.
An index value passed to the methods must be one of sbmp:: constants:
sbmp::Logo sbmp::CheckBoxChecked sbmp::CheckBoxCheckedPressed sbmp::CheckBoxUnchecked sbmp::CheckBoxUncheckedPressed sbmp::RadioChecked sbmp::RadioCheckedPressed sbmp::RadioUnchecked sbmp::RadioUncheckedPressed sbmp::Warning sbmp::Information sbmp::Question sbmp::OutlineCollaps sbmp::OutlineExpand sbmp::Error sbmp::SysMenu sbmp::SysMenuPressed sbmp::Max sbmp::MaxPressed sbmp::Min sbmp::MinPressed sbmp::Restore sbmp::RestorePressed sbmp::Close sbmp::ClosePressed sbmp::Hide sbmp::HidePressed sbmp::DriveUnknown sbmp::DriveFloppy sbmp::DriveHDD sbmp::DriveNetwork sbmp::DriveCDROM sbmp::DriveMemory sbmp::GlyphOK sbmp::GlyphCancel sbmp::SFolderOpened sbmp::SFolderClosed sbmp::Last
$sysimage scalar is initialized to the file name to be used
as a source of standard image frames by default. It is possible
to alter this scalar at run-time, which causes all subsequent
image frame request to be redirected to the new file.
