Newbie problem with qsa
Message 1 in thread
Hi
I am a new user of qsa (1.2.0 using qt 4.0.1 & snapshot 29/10). I am
having trouble using it. Actually i am just using it in a dummy app to
get a feel of it. Here is the code (shortened):
QsaTrial::QsaTrial() : QWidget(0){ //This is main window
this->setObjectName("trial");
m_pButton1 = new QPushButton("First", this);
m_pButton1->setObjectName("button");
m_pButton2 = new QPushButton("Second", this);
m_pButton2->setObjectName("buttons");
m_pButton2->move(20, 0);
resize( 200, 200);
qsProject = new QSProject(this);
qsProject->addObject(this);
qsInterpreter = qsProject->interpreter();
qsInterpreter->addObject(this);
tmr = new QTimer (this);
connect(tmr, SIGNAL(timeout()), this, SLOT(tmrHandler()));
tmr->start(5000);
}
void QsaTrial::tmrHandler(){
qsInterpreter->evaluate("trial.button.visible = !trial.button.visible;");
qsInterpreter->evaluate("trial.buttons.visible = !trial.buttons.visible;");
}
Problem with the above code is that only the button which is
initialised first is available to the script. e.g. in the above code
"Error: Trying to access undefined member 'buttons'" is generated.
If m_pButton2 is initialised first then 'buttons' is available in qsa
but 'button' is not.
I guess am not doing something usual.
Please help me.

Please ignore/comment the following line in my prev mail:
qsInterpreter->addObject(this);
Sorry for the mistake.
