NAME ^

Prima::StdBitmap - shared access to the standard toolkit bitmaps

DESCRIPTION ^

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.

SYNOPSIS ^

        use Prima::StdBitmap;
        my $logo = Prima::StdBitmap::icon( sbmp::Logo );

API ^

Methods

icon INDEX

Loads INDEXth image frame and returns Prima::Icon instance.

image INDEX

Loads INDEXth image frame and returns Prima::Image instance.

load_std_bmp INDEX, AS_ICON, USE_CACHED_VALUE, IMAGE_FILE

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.

Constants

An index value passed to the methods must be one of sbmp:: constants:

        sbmp::Logo
        sbmp::CheckBoxChecked
        sbmp::CheckBoxCheckedPressed
        sbmp::CheckBoxUnchecked

        sbmp::MaxPressed
        sbmp::Min
        sbmp::MinPressed
        sbmp::Restore
        sbmp::RestorePressed
        sbmp::Close
        sbmp::ClosePressed

        sbmp::DriveNetwork
        sbmp::DriveCDROM
        sbmp::DriveMemory

        sbmp::GlyphCancel
        sbmp::SFolderOpened
        sbmp::SFolderClosed
        sbmp::Last

Scalars

$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.
