Bug 31551 – QEvent::RequestSoftwareInputPanel only sent second time an input field is clicked

• Component: Forms
• Status: RESOLVED INVALID

[Henrik Hartz]

When clicking a user input field, only reclick gives a RequestSoftwareInputPanel event. The first click should report the same if the caret is activated inside the input field, to allow touch interfaces to raise a virtual keyboard. However, only the second click will cause a QEvent of type RequestSoftwareInputPanel to be delivered.

Tested with Qt 4.6 prerelease

The following example demonstrates the bug;

<pre>
#include <QtGui>
#include <QtWebKit>
#include <QDebug>

class CustomWidget : public QWebView
{ Q_OBJECT
public:
    CustomWidget(QWidget* parent=0) : QWebView(parent)
    {
        load(QUrl("http://google.com"));
    }

protected:
    bool event( QEvent *e )
    {
        bool returnValue = QWebView::event(e);
        if (e->type()==QEvent::RequestSoftwareInputPanel)
            qDebug() << "Software Input Panel Requested"
        return returnValue;
    }
};

#include "main.moc"

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    CustomWidget wid;
    wid.show();

    return app.exec();
}
</pre>

[Janne Koskinen]

This is a feature of focusing, or how did you think of selecting text if fullscreen keyboard is always brought on screen? we can discuss this further.

I believe this is not a WebKit bug but simply a style dependent behaviour. See also http://doc.qt.nokia.com/4.6-snapshot/qstyle.html#RequestSoftwareInputPanel-enum

The code in WebKit that triggers sending the RSIP event queries the style for this style hint and if the style returns RSIP_OnMouseClick, then the RSIP is sent on a single mouse click.

I wonder however if we should perhaps change our default in QCommonStyle....
