Prima::Widgets - miscellaneous widget classes
DESCRIPTION
The module was designed to serve as a collection of small widget classes that do not group well with the other, more purposeful classes.
The current implementation contains the only class, "Prima::Panel".
Prima::Panel
Provides a simple panel widget, capable of displaying a single line of centered text on a custom background. Probably this functionality is
better to be merged into "Prima::Label"'s.
Properties
borderWidth INTEGER
Width of 3d-shade border around the widget.
Default value: 1
image OBJECT
Selects image to be drawn as a tiled background. If "undef", the background is drawn with the background color.
imageFile PATH
Set the image FILE to be loaded and displayed. Is rarely used since does not return a loading success flag.
raise BOOLEAN
Style of 3d-shade border around the widget. If 1, the widget is 'risen'; if 0 it is 'sunken'.
Default value: 1
zoom INTEGER
Selects zoom level for image display. The acceptable value range is between 1 and 10.
Default value: 1

Prima::noX11(3) User Contributed Perl Documentation Prima::noX11(3)NAME
Prima::noX11 - Use Prima without X11
SYNOPSIS
use Prima::noX11;
use Prima;
my $error = Prima::XOpenDisplay();
if ( defined $error) {
print "not connected to display: $error
";
} else {
print "connected to display
";
}
DESCRIPTION
Prima will by default connect to X11 server on unix. To use Prima functionality in modules or programs where this default behavior is
undesired, please follow the guidelines below.
No connection
In the beginning of a script or a module that is never intended to connect to X11 display, add this:
use Prima::noX11;
use Prima;
It will be possible to connect to X11 server later on manually.
Manual connect to X11
If connection to X11 is optional, use this code after "use Prima::noX11" was invoked:
my $error = Prima::XOpenDisplay();
if ( defined $error) {
print "not connected to display: $error
";
} else {
print "connected to display
";
}
Checking if GUI functionality is accesiible.
Without X11 connection, no GUI functionality such as screen grabbing will be accessible. In addition to that functionality, windowing
functions will only become accessible after Prima::Application creates a single instance $::application.
Therefore, if $::application is defined, then all GUI functions can be safely used. If, on the contrary, it is not defined, initiate it as
this:
unless ( $::application) {
my $error = Prima::XOpenDisplay();
die $error if defined $error;
require Prima::Application;
import Prima::Application;
}
