Qt &QSS

Today task：
解决了qt中的一些控件无法使用qss的问题（如QProgressDialog 调节chunk的颜色，QMessageBox按钮的颜色问题）
1，对于QMessageBox，可以单独设置Button的qss
如：style += QPushButton(color: rgb(...), backround-color: rgb(...); height: 12px };
可是，有些时候，字体颜色无法使用qss所规定的
那么可以使用一下方法来使其生效。

 QObjectList objectChildList = msgBox->children();
 for(int i=; i<objectChildList.size(); i++)
 {
 
         QObject *pObj= objChildList.at(i);
         if (pObj->inherits("QLabel"))
         {
             QWidget *pWidget = (QWidget*)pObj;
             pWidget->setStyleSheet("color: rgb(255,255,255)");
         }
 }

然后设置其sytle。

对于QProgressDialog

     style +="QProgressDialog{ background-color: rgb(108, 110, 108)}";
     style +="QPushButton{color: rgb(255,255,255); background-color: rgb(66, 66, 66);height: 14px; width: 100px}";
     style +="QPushButton::hover{color: rgb(255,255,255); background-color: rgb(74, 74, 74);height: 14px; width: 100px}";
 
     QObjectList objChildList = qPDlg->children();
     for (int i = ; i < objChildList.size(); i++)
     {
         QObject *pObj= objChildList.at(i);
         if (pObj->inherits("QProgressBar"))
         {
             QWidget *pWidget = (QWidget*)pObj;
             QProgressBar *pBWidget = (QProgressBar *)pWidget;
             QString sheet;
             sheet += "QProgressBar{color: rgb(255,255,255); background-color:rgb(48, 48, 48);border-radius: 2px;}";
             sheet += "QProgressBar::chunk{background-color:rgb(176,138,32);}";
             pWidget->setStyleSheet(sheet);
             pBWidget->setAlignment(Qt::AlignCenter);
         }
         else if (pObj->inherits("QLabel"))
         {
             QWidget *pWidget = (QWidget*)pObj;
             pWidget->setStyleSheet("color: rgb(255,255,255)");
         }
     }

3, QTreeView stylesheet

         QString style;
         style +="QTreeView::Item{background-color:rgb(66, 66, 66);}";
          style +="QTreeView::Item::selected{background-color:rgb(0,54,162);}";
         style +="QTreeView::Item{color: rgb(255, 255, 255);}";
 
         style +="QTreeView::branch:has-siblings:!adjoins-item {background:rgb(0,54,162);}";
         style +="QTreeView::branch:has-siblings:adjoins-item {background:rgb(0,54,162);}";
         style +="QTreeView::branch:!has-children:!has-siblings:adjoins-item {background:rgb(66, 66, 66);}";
         style +="QTreeView::branch:has-children:!has-siblings:closed {background:rgb(108, 110, 108);}";
         style +="QTreeView::branch:has-children:!has-siblings:closed:selected {background:rgb(0,54,162);}";
 
         style +="QTreeView::branch:open:has-children:!has-siblings:selected {background:rgb(0,54,162);}";
         style +="QTreeView::branch:open:has-children:has-siblings:selected {background:rgb(0,54,162);}";//>>>>>>>>>>>>
 
 //        style +="QTreeView::branch:close:has-children:!has-siblings {background:rgb(108, 110, 108);}";
      //   style +="QTreeView::branch:close:has-children:!has-siblings:selected {background:rgb(108, 110, 108);}";
         style +="QTreeView::branch:close:has-children:has-siblings {background:rgb(66, 66, 66);}";
        // style +="QTreeView::branch:close:has-children:has-siblings:selected {background:rgb(0,54,162);}";
 
         style +="QTreeView::branch:has-siblings:!adjoins-item {border-image: url(:/Icons/stylesheet-vline.png) 0;}";
 
         style +="QTreeView::branch:has-siblings:adjoins-item {border-image: url(:/Icons/stylesheet-branch-more.png) 0;}";
 
         style +="QTreeView::branch:!has-children:!has-siblings:adjoins-item {border-image: url(:/Icons/stylesheet-branch-end.png) 0 }";
 
         style +="QTreeView::branch:has-children:!has-siblings:closed,QTreeView::branch:closed:has-children:has-siblings {border-image: none;image: url(:/Icons/stylesheet-branch-closed.png);}";
 
         style +="QTreeView::branch:open:has-children:!has-siblings,QTreeView::branch:open:has-children:has-siblings  {border-image: none;image: url(:/Icons/stylesheet-branch-open.png);}";
 
         style += "QTreeView{background: rgb(66, 66, 66);}";
         style += "QTreeView::HeaderView{background: rgb(66, 66, 66);}";
 
         style += "QHeaderView::section {background-color:rgb(66, 66, 66);color: white; border: 0 px; font-weight: bold;}";
         style += "QWidget{background: rgb(66, 66, 66); color: white;}";
         setStyleSheet(style);
