C++ (Cpp) KateView::cursorLeft Examples

Example #1

File: bug294756.cpp Project: azat-archive/kate

void BugTest::tryCrash()
{
  KateDocument doc(false, false, false);
  QString url = KDESRCDIR + QString("data/folding-crash.py");

  doc.discardDataRecovery();
  doc.setHighlightingMode("Python");
  doc.buffer().ensureHighlighted (doc.lines());

  // view must be visible...
  KateView* view = static_cast<KateView*>(doc.createView(0));
  view->show();
  view->resize(400, 300);

  // fold all
  doc.foldingTree()->collapseToplevelNodes();
  QTest::qWait(1000);

  view->down();
  view->down();
  view->down();
  view->cursorLeft();
  QTest::qWait(1000);

  qDebug() << "!!! The next line usually crashes in the code folding code";
  view->backspace();

  doc.buffer().ensureHighlighted (doc.lines());
