Using QProcess..........

[sar_van81]

hi....

i had created an application which has pushbuttons. when i click a pushbutton, a web browser should open(i had built konqueror embedded web browser compiled with qvfb option). this is my requirement. but when i execute the program, the web browser opens,but website is not displayed,instead a blank page is displayed. when i close the application, the webpage is displayed...

can anyone say me why is that so...?any suggestions and solutions fro this...?

thanks in advance......

We'd have to see the code you used to open the page.

void keyclass::enter()
{
 
   QProcess process(QString("/home/kdeprograms/konqueror/konqueror3-embedded-0.2-20060121/konq-embed/src/konqueror"));
   process.addArgument("http://www.yahoo.com");
   process.start();
 }

void keyclass::enter()
{
 
   QProcess process(QString("/home/kdeprograms/konqueror/konqueror3-embedded-0.2-20060121/konq-embed/src/konqueror"));
   process.addArgument("http://www.yahoo.com");
   process.start();
 }

You create the process on the stack. QProcess::start() doesn't block the flow until the process exits but instead just schedules its start and continues the program. At that time the function returns and the process gets destroyed before it even had a chance to start. To avoid it, you have to create the process on heap.

hi....

thanks for the reply. can you say me how create the process on a heap...?

Using operator "new".

QProcess *process = new QProcess(this);

QProcess *process = new QProcess(this);

To copy to clipboard, switch view to plain text mode
