POQt for Embedded Linux: Hide cursor on startup
text
Body
copied!<p>I'm developing a Qt application on a linux embedded system. The system has got a touchscreen, but also an OTG USB port, and it must be usable with a mouse.</p> <p>So my problem is, when the application starts, it shows a mouse cursor in the middle of the screen, and then it disapears when my main windows paint event occurs.</p> <p>When the application has started, I can hide/show the cursor if a mouse is plugged in, that works great, but I always have the cursor during the startup.</p> <p>I tried: QWSServer::setCursorVisible(false);</p> <p>or: qApp->setOverrideCursor(QCursor(Qt::BlankCursor));</p> <p>and the result is the same as described above.</p> <p>The only way I found to hide the cursor during startup was compiling Qt without the Cursor, but then I can't have a cursor when the mouse is plugged in (that's logic...).</p> <p>So if you have an idea, I would be happy to read it :-)</p> <p>Thanks, Sylvain</p> <p>EDIT: Okey so that's the QWS Server that shows the cursor on startup, I found that in qt/src/gui/embedded/qwscursor_qws.cpp:</p> <pre><code>void QWSServerPrivate::initializeCursor() { Q_Q(QWSServer); // setup system cursors #ifndef QT_NO_QWS_CURSOR // qt_screen->initCursor(sharedram + ramlen,true); // default cursor cursor = 0; setCursor(QWSCursor::systemCursor(Qt::ArrowCursor)); #endif q->sendMouseEvent(QPoint(swidth/2, sheight/2), 0); } </code></pre> <p>Now if I comment the "setCursor" instruction, that solves the problem, but that's kind of ugly to edit Qt source code to do that, so if you've got a better solution...</p>
