I am developing a virtual keyboard with Qt Embedded, and I'm confronted with a little problem. In fact, I use SignalMappers to map the key to keyboard events in order to display text in a QTextEdit widget.
Everything works fine, except for two events : Key_Return and Key_Delete ; I have no idea what I'm doing wrong, maybe you'll have an idea.
Here is a classical code, to send chars :
void VirtualKeyboard::SendChar( int index ) { QChar charToSend( letters_.at( index )->text().at( 0 ) ); // Get char server_->sendKeyEvent( charToSend.unicode(), QEvent::KeyPress, Qt::NoModifier, true, false ); } letters_ is a QVector containing QPushButton* and server_ is the instance of QWSServer ; this code works fine. Now, for example with backspace :
void VirtualKeyboard::SendBackspace() { server_->sendKeyEvent( Qt::Key_Backspace, Qt::Key_Backspace, Qt::NoModifier, true, false ); } This code works fine too. And the code that doesn't work :
void VirtualKeyboard::SendDelete() { server_->sendKeyEvent( Qt::Key_Delete, Qt::Key_Delete, Qt::NoModifier, true, false ); } void VirtualKeyboard::SendEnter() { server_->sendKeyEvent( 0x01000004, Qt::Key_Return, Qt::NoModifier, true, false ); } As you can see, I tryed to put an unicode value but it doesn't help ; can you help me please ?
Thanks !
SOLVED WITH THE FOLLOWING CODE (SEE COMMENT) :
void TextEdit::DeleteEvent() { if( cursor_.hasSelection() ) { // Delete selection cursor_.removeSelectedText(); } else { // Delete right char cursor_.deleteChar(); } setTextCursor( cursor_ ); } void TextEdit::ReturnEvent() { cursor_.insertText( "\n" ); setTextCursor( cursor_ ); } cursor_ is a QTextCursor attribute, initialized with this line :
cursor_ = textCursor();
