Good morning and thank you for your answer.
I found the kate plugin example, and i applied it to my code.
The problem is that i am missing something probably...
In fact, my application at startup says:
Fatal error: you need to have a KComponentData object before
you do anything that requires it! Examples of this are config
objects, standard directories or translations.
My main window class is declared like this:
class IQFIREmainwin : public KParts::MainWindow
{ ... };
and the constructor does:
IQFIREmainwin::IQFIREmainwin(QWidget* p, int argc, char **argv) :
KParts::MainWindow()
{
ui.setupUi(this);
CreateSystemTray();
...
/* ui.pageConsole is a page of a QT Stacked widget */
QGridLayout *consolelo = new QGridLayout(ui.pageConsole);
IQFWidgetKonsole* iqfconsole = new IQFWidgetKonsole(ui.pageConsole);
consolelo->addWidget(iqfconsole, 0, 0);
/* IQFWidgetKonsole is the widget that contains the part */
ui.stackedWidgetMain->setCurrentWidget(ui.pageConsole);
}
class IQFWidgetKonsole : public QWidget
{
public:
IQFWidgetKonsole(QWidget *parent);
~IQFWidgetKonsole();
};
IQFWidgetKonsole::IQFWidgetKonsole(QWidget *parent)
{
KLibFactory* factory = KLibLoader::self()->factory( "libkonsolepart" );
qDebug() << "IQFWidgetKonsole() : constructor";
if ( factory == 0L )
{
// inform the user that he should install konsole..
QMessageBox::information(this, "Information",
"You need to install konsole!");
return;
}
KParts::ReadOnlyPart *part = static_cast<KParts::ReadOnlyPart *>
(factory->create(this, "KParts::ReadOnlyPart"));
// start the terminal
qobject_cast<TerminalInterface*>(part)->showShellInDir( QString() );
}
i am missing something substantial...
but i am new in kde programming and, most of all, i did not find some
startup tutorial...
Thank you for any hint..
