C++ (Cpp) QProcess::setCommunication Examples

Example #1

File: qucs_actions.cpp Project: MikeBrinson/qucs

// --------------------------------------------------------------
void QucsApp::showHTML(const QString& Page)
{
  QStringList com;
  com << QucsSettings.BinDir + "qucshelp" << Page;
  QProcess *QucsHelp = new QProcess(com);
  QucsHelp->setCommunication(0);
  if(!QucsHelp->start()) {
    QMessageBox::critical(this, tr("Error"), tr("Cannot start qucshelp!"));
    delete QucsHelp;
    return;
  }

  // to kill it before qucs ends
  connect(this, SIGNAL(signalKillEmAll()), QucsHelp, SLOT(kill()));
}

Example #2

File: qucs_actions.cpp Project: MikeBrinson/qucs

// ------------------------------------------------------------------------
// Is called by slotShowLastMsg(), by slotShowLastNetlist() and from the
// component edit dialog.
void QucsApp::editFile(const QString& File)
{
  QStringList com;
  com << QucsSettings.Editor;
  if (!File.isEmpty()) com << File;
  QProcess *QucsEditor = new QProcess(com);
  QucsEditor->setCommunication(0);
  if(!QucsEditor->start()) {
    QMessageBox::critical(this, tr("Error"), tr("Cannot start text editor!"));
    delete QucsEditor;
    return;
  }

  // to kill it before qucs ends
  connect(this, SIGNAL(signalKillEmAll()), QucsEditor, SLOT(kill()));
}

Example #3

{
    QStringList argv = tasks.front();
