File Properties Dialog

Set font style

 Get file information

Show file properties dialog

When we click on the properties in the file, a properties dialog box will pop up: 

 

Implementation process:

0. Set the slot function of the property menu item .

1. The mouse gets the QListWidgetItem selected by the mouse , which contains the icon and file name.

2. Find the corresponding FileInfo object according to the file name

ps: FileInfo is a file information object. In the process of displaying the file list, the file information of each file has been saved to QList<FileInfo*> m_fileInfoList

3. Set the information in the FileInfo object into the file properties dialog box. 

File Properties Dialog

 Implementation process:

Customize a filePropertyiInfoDialog type and inherit the QDialog type, including

filePropertyiInfoDialog.h， filePropertyiInfoDialog.cpp ,filePropertyiInfoDialog.ui文件

filePropertyiInfoDialog.ui interface design:

 

Set font style

 filePropertyiInfoDialog.cpp, set the font color in the constructor:

filePropertyiInfoDialog::filePropertyiInfoDialog(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::filePropertyiInfoDialog)
{
    ui->setupUi(this);
    QString style1 = QString("color: rgb(11, 11, 11);font: 75 14pt \"Agency FB\";");
    QString style2 = QString("font: 14pt \"隶书\";color: rgb(255, 156, 16);");

    this->setWindowTitle("文件属性");
    ui->lbl_fileName->setStyleSheet(style1);
    ui->lbl_fileSize->setStyleSheet(style1);
    ui->lbl_download->setStyleSheet(style1);
    ui->lbl_shareStatus->setStyleSheet(style1);
    ui->lbl_uploadTime->setStyleSheet(style1);
    ui->lbl_uploadUser->setStyleSheet(style1);

    ui->val_fileName->setStyleSheet(style2);
    ui->val_fileSize->setStyleSheet(style2);
    ui->val_download->setStyleSheet(style2);
    ui->val_shareStatus->setStyleSheet(style2);
    ui->val_uploadTime->setStyleSheet(style2);
    ui->val_uploadUser->setStyleSheet(style2);

}

 Get file information

    //设置属性菜单项的槽函数
    connect(m_propertyAction,&QAction::triggered,this,[=]{
        dealfile(DealFile::Show);
    });


void myfile::dealfile(DealFile cmd)
{
    //获取鼠标选中的QListWidgetItem
    QListWidgetItem* item=ui->listWidget->currentItem();

    for(int i=0;i<m_fileInfoList.length();i++)
    {
        //根据文件名找到对应的文件信息
        FileInfo* fileInfo=m_fileInfoList[i];
        if(fileInfo->fileName==item->text())
        {

           if(cmd==DealFile::Show)
            {
                //显示文件属性
                showFileProperty(fileInfo);
            }
        }
    }
}
