Perl Qt bindings

[Rog131]

The Perl Qt bindings are available for the Ubuntu 11.04 or later > libqtcore4-perl, > libqtgui4-perl.


Installing the libqtgui4-perl and a short perl script:

#!/usr/bin/perl -w

use strict;
use warnings;
use QtCore4;
use QtGui4;


my $app = Qt::Application(\@ARGV);

my $window = Qt::Widget();
$window->resize(200, 120);

my $quit = Qt::PushButton(Qt::String("Click Me"), $window);
$quit->setGeometry(10, 40, 180, 40);
$app->connect($quit, SIGNAL('clicked()'), $app, SLOT('quit()'));

$window->show();
$app->exec();

QML from a Perl script

The QML interface can be called from the Perl or the Python scripts.

From a Perl script:

/media/sda3/QML/Perl-QML-ThumbFlow/thumbflow.pl

#!/usr/bin/perl

use strict;
use warnings;

use QtCore4;
use QtGui4;
use QtDeclarative4;


my $app = Qt::Application(\@ARGV);

my $window = Qt::DeclarativeView();
$window->setSource(Qt::Url("/media/sda3/QML/Perl-QML-ThumbFlow/main.qml"));

$window->show();
$app->exec();

The QML (coverflow ~ thumbflow) code is from: http://projects.developer.nokia.com/QMLTemplates

Dependencies: libqtgui4-perl, libqtdeclarative4-perl.

@Rog131,
I don't know perl, but pretty good with Qt. Normally you would have a layout in between your main widget and the button. Something like:

//sudo code
button = new QPushButton(...)
layout = new QHBoxLayout(...)
widget = new QWidget(...)

layout->addWidget(button)
widget->setLayout(layout)
widget->show()

With this set up I think you can get rid of 1, and maybe both, of your geometry/resize calls. This will also allow the dynamic resizing to behave, which I am guessing right now doesn't behave.
