QWebView and special character like @

**foo6321** · 2010-03-01, 15:36

Hi!

I am trying to run a test application that uses QWebView for asking a text entry.
I am able to type any characters in the text entry on the N900, but special character like "@" (character 2 is appearing instead) just doesn't appears in the Fremantle SDK on my desktop.
I am using Qt4.6 for Maemo5

Here is the code
qwebview.pro:

Code:

TEMPLATE = app
TARGET = qwebview
DEPENDPATH += .
INCLUDEPATH += .
CONFIG += qt debug
QT += network webkit

HEADERS += qwet.h 
SOURCES += main.cpp qwet.cpp

RESOURCES += qwebview.qrc

qwebview.qrc:

Code:

<RCC>
    <qresource prefix="/">
        <file>html/view.html</file>
        <file>css/view.css</file>
    </qresource>
</RCC>

Code:

#ifndef QWET_H
#define QWET_H
 
#include <QtCore/QPointer>
 
#include <QtWebKit/QWebView>
#include <QtWebKit/QWebPage>
#include <QtWebKit/QWebFrame>
 
#include <QtGui/QWidget>
#include <QtGui/QApplication>
#include <QtGui/QMainWindow>
#include <QtGui/QFrame>
#include <QtGui/QVBoxLayout>
 
class QWET : public QMainWindow
{
    Q_OBJECT
 
public:
    QWET(QWidget *parent = 0);
 
private:
    QPointer<QWebView> _webView;
    QPointer<QVBoxLayout> _layout;
};
 
#endif // QWET_H

qwet.cpp:

Code:

#include "qwet.h"
 
QWET::QWET(QWidget *parent) : QMainWindow(parent) 
{
    QFrame* cW = new QFrame(this);
    setCentralWidget(cW);
 
    _layout = new QVBoxLayout(this);
    cW->setLayout(_layout);
    _layout->setMargin(0);
    _layout->setSpacing(0);
 
    _webView = new QWebView(this);
    _webView->load(QUrl("qrc:///html/view.html"));
    _webView->show();
 
    _layout->addWidget(_webView);
}

css/view.css:

Code:

@CHARSET "UTF-8";
 
html {
    background-color: lightgray;
    margin: 1em 0 0 1em;
    padding: 0;
}
 
body {
    margin: 0;
    padding: 0;
}
 
h1#header {
    color: black;
    margin: 0;
    padding: 0;
}
 
p {
    color: black;
    margin: 0 0 0 5pt;
    padding: 0;
}
 
form#form {
    color: black;
    margin: 0 0 0 5pt;
    padding: 0;
}
 
fieldset {
    border: 0;
}

Code:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

    <!-- Stylesheet reference -->
    <link rel="stylesheet" href="qrc:///css/view.css" />
 
    <title>WebKit example</title>
  </head>
  <body>
    <!-- Header -->
    <h1 id="header">Welcome</h1>
    <!-- Paragraph -->
    <p id="paragraph">Hello World!</p>
    <!-- Form -->
    <form id="form" action="#">
      <fieldset>
        <label for="text">Text</label>
        <!-- Text input -->
        <input id="text" type="text" />
        <!-- Submit button -->
        <input id="button" type="button" value="Submit!"/>
      </fieldset>
    </form>
  </body>
</html>

Do I have to set something in my Scratchbox target, the in Hildon desktop, or I have to set some QWebView settings ?

Thanks

Ok, I don't think my issue is related to QWebView: I have tried to type "@" in the "Account Setup" dialog of the Maemo Address book and the character doesn't appears.

You issue is not related to Qt. It's actually Xephyr bug. What is version of your Linux distribution, xserver-xephyr you have and what is an exact command you use to start Xephyr?

**foo6321** · 2010-03-02, 08:37

I am developing on Ubuntu 9.10 Karmic Koala and xephyr version is 2:1.6.4-2ubuntu4.1
My xephyr command is : Xephyr :2 -host-cursor -screen 800x480x16 -dpi 96 -ac -kb

There is a small test app:

Code:

/*  Compile with:
 *  gcc -Wall -g events.c -o events $(pkg-config --cflags --libs gtk+-2.0)
 */

#include <X11/Xlib.h>
#include <X11/Xatom.h>
#include <stdlib.h>
#include <string.h>
#include <glib.h>
#include <gdk/gdkx.h>
#include <gdk/gdkkeysyms.h>
#include <gdk/gdkx.h>
#include <gtk/gtk.h>

static void
set_zoom_atom (GtkWidget *window,
               gint state)
{
        GdkWindow      *gdk_window;
        GdkDisplay     *display;

        state = state > 0 ? 1 : 0;

        gdk_window = window->window;
        if (!gdk_window) {
                g_print ("Not available window\n");
                return;
        }
        display = gdk_drawable_get_display ((GdkDrawable*)gdk_window);
        if (!display) {
                g_print ("Not available display\n");
                return;
        }
        XChangeProperty (GDK_DISPLAY_XDISPLAY (display),
                         GDK_WINDOW_XID (gdk_window),
                         gdk_x11_get_xatom_by_name_for_display
                                        (display, "_HILDON_ZOOM_KEY_ATOM"),
                         XA_INTEGER, 32, PropModeReplace,
                         (unsigned char*) &state, 1);
}


static gboolean
key_cb (GtkWidget   *widget,
        GdkEventKey *event,
        gpointer     user_data)
{
        const gchar *msg;

        switch (event->type) {
        case GDK_KEY_PRESS:
                msg = "press";
                break;
        case GDK_KEY_RELEASE:
                msg = "release";
                break;
        default:
                msg = "unknown";
                break;
        }
        g_print ("%s\tstate[0x%x]\tkey[0x%x]\n", msg, event->state, event->keyval);

        return FALSE;
}



static void
destroy_cb (GtkWidget *widget,
            gpointer   data)
{
        gtk_main_quit ();
}


gint
main (gint argc,
      gchar **argv)
{
        GtkWidget *window;

        gtk_init (&argc, &argv);

        window = gtk_window_new (GTK_WINDOW_TOPLEVEL);

        g_signal_connect (G_OBJECT (window), "delete-event",
                          G_CALLBACK (destroy_cb), NULL);
        g_signal_connect (G_OBJECT (window), "key-press-event",
                          G_CALLBACK (key_cb), NULL);
        g_signal_connect (G_OBJECT (window), "key-release-event",
                          G_CALLBACK (key_cb), NULL);

        gtk_widget_show_now (window);
        gdk_window_set_events (window->window,
                               GDK_KEY_PRESS_MASK | GDK_KEY_RELEASE_MASK);

        set_zoom_atom (window, 1);

        gtk_main ();

        exit (0);
}

You can see that AltGr modifier (I use Swedish keyboard) is not taken into account in scratchbox. I guess the issue with key maps inside X86 scratchbox target.

Ok, thanks, I've filled a bug to Maemo SDK
https://bugs.maemo.org/show_bug.cgi?id=9364

**divanov** · 2010-03-02, 14:59

Elvis?

Well, there is no Finnish keyboard, only Swedish one
