如何在perl中使用Qt GUI(使用Qt Designer创建)？

我在Qt Designer中创建了Qt GUI并将其编译(使用puic4)到gui.pm.
现在,我想在我的Perl应用程序中使用它,但是因为我不知道如何创建窗口对象而被卡住了.

我在start.pl中有以下代码：

use strict;
use QtCore4;
use QtGui4;
use gui; #compiled gui ('Ui_MainWindow' package)

my $a = Qt::Application(\@ARGV);
my $w = ??? #assign window object to $w

$w->show();
exit $a->exec();

我只需要创建窗口对象,但我找不到用perl编写的任何示例.有人可以帮帮我吗？

解决方法

我在源代码库中找到了以下解决方案：

BUILD_DIR/Qt4-0.99.0/qtgui/examples/designer/calculatorform

>构建您的Ui模块

> puic4 Window.ui -o Ui_MainWindow.pm

package MainWindow;

use QtGui4;
# Cast the exact Qt Type for your UI class
use QtCore4::isa qw( Qt::MainWindow );

use Ui_MainWindow;

sub NEW {
  my ( $class,$parent ) = @_;
  $class->SUPER::NEW($parent);
  this->{ui} = Ui_MainWindow->setupUi(this);
}

use strict;

use QtCore4;

sub main {

   my $win = MainWindow();
   $win->show();
  exit $app->exec();
}

main();

哈哈
