qtopia中程序( videos music等)的修改

板子：helper2416     qtopia2/3      作者:帅得不敢出门   c++哈哈堂:31843264 

例子1:          修改工具栏, 比如添加一个关闭按钮

修改qtopia-2.2.0/qtopia/src/libraries/mediaplayer/mediaselectorwidget.cpp

class MediaSelectorWidgetPrivate { 

中添加

Action *tbQuit;

构造函数中

MediaSelectorWidget::MediaSelectorWidget

    d->tbAdd     = new Action( this, tr( "Add to Category..." ), "categorize",this, SLOT(categorize()) );下一行添加
    d->tbQuit    = new Action( this, tr( "Quit" ), "close", qApp, SLOT(quit()) );

    d->tbAdd->addTo(contextMenu); 下一行添加
    d->tbQuit->addTo(contextMenu);

    d->tbDown->addTo( d->bar ); 下一行添加
    d->tbQuit->addTo( d->bar );

然后在qtopia/pics/icons/ 下的各文件夹加close.png就行了.

注意修改libraries/mediaplayer 下的文件会同时影响videos 与music

例2   播放音视频的窗口中滑动条与时间控件的右边添加关闭按钮

qtopia/src/libraries/mediaplayer/controlwidgetbase.h中添加

#include

    QPushButton *closeBtn;

qtopia/src/libraries/mediaplayer/controlwidgetbase.cpp 中

1

ControlWidgetBase::ControlWidgetBase( QWidget* parent, const QString &skinPath,
                        const QString &type, const char* name ) :
    QWidget(parent, name), buttonCount(0), slider(Qt::Horizontal, this),
    time(this), sliderBeingMoved(false), volumeTimeout(this), drawVolume(false)
{
    setCaption( tr("Media Player") );
     // 添加下面这一行
    closeBtn = new QPushButton( tr("close"), this);

2

   connect( &slider,           SIGNAL( sliderPressed() ),      this, SLOT( sliderPressed() ) );
   connect( &slider,           SIGNAL( sliderReleased() ),     this, SLOT( sliderReleased() ) );
//添加下面这行
   connect( closeBtn,          SIGNAL( pressed() ),            this, SLOT( close() ) );

3

imgButtonMask.fill( 0 );
//  此行下面修改如下
int closeBtnW = 48;
int y1 = h - timeHeight - 2 * border;
int x2 = w - timeWidth - border - cornerWidgetWidth - closeBtnW - border;
QRect sliderGeometry( border, y1, x2 - 2*border, timeHeight );
QRect timeGeometry( x2, y1, timeWidth, timeHeight );
QRect closeBtnGeometry( x2 + timeWidth + border, y1, closeBtnW, timeHeight);
getRect(cfg, skinType+"_slider", sliderGeometry, w, h);
getRect(cfg, skinType+"_time", timeGeometry, w, h);

slider.setGeometry(sliderGeometry);
time.setGeometry(timeGeometry);
closeBtn->setGeometry(closeBtnGeometry);

然后先编译libmediaplayer.so

再分别编译musi 与videos, 如果不重新编译运行会出现段错误.

就可以了.

例3:   给photoEdit的sider_show窗口添加 确定 与取消两个按钮

qtopia/src/applications/photoedit/slideshow/slideshowdialog.h

包含头

#include

private:
    QLabel *slide_length_label;
    QSlider *slide_length_slider;
    QCheckBox *display_name_check, *loop_through_check;
//添加下面这行
    QPushButton *ok_button, *cancel_button;

qtopia/src/applications/photoedit/slideshow/slideshowdialog.cpp

// Construct loop through label and check box
loop_through_check = new QCheckBox( tr( "Loop through" ), this );
vbox->addWidget( loop_through_check );
nbsp;

// 加上下面这段
// Construct ok cancel buttons JYX_MODI add
QHBoxLayout *hbox = new QHBoxLayout;
ok_button = new QPushButton( tr( "Ok" ), this );
cancel_button = new QPushButton( tr( "Cancel" ), this );
connect( ok_button, SIGNAL( pressed() ), this, SLOT( accept() ) );
connect( cancel_button, SIGNAL( pressed() ), this, SLOT( reject() ) );
hbox->addWidget( ok_button );
hbox->addWidget( cancel_button );
vbox->addLayout( hbox );
// JYX_MODI add end

重新编译photoEdit便可.
