my concern is same data to be printed on text browser on qt
@siva9111 Come on - this is really not that hard. You just need to pass the URL to your file to QTextBrowser::setSource and it will load the content of your XML file...
To get the URL to your file use https://doc.qt.io/qt-5/qurl.html#fromLocalFile -
-
this is working :
QUrl url=QUrl::fromLocalFile("C:/Users/Administrator/Desktop/siva.txt");
ui.textBrowser->setSource(url);this not loading:
QUrl url=QUrl::fromLocalFile("C:/Users/Administrator/Desktop/xmlinfo.xml");
ui.textBrowser->setSource(url); -
if(url.isValid()){
QMessageBox::information(0,"info",url.errorString());
}iam executed above code ....messagebox displayed
(due to new user iam unable to replying to you sir....its taking 10min time for next reply ...see ur inbox sir)
@siva9111 Does it work if you use https://doc.qt.io/qt-5/qtextedit.html#setPlainText instead of setSource?
