@Alain38-0 said in Problem with QTest, QGlWidget, and Qt5:
I have found a similar problem in my application
Please provide a Short, Self Contained, Correct (Compilable), Example (http://www.sscce.org/ ). Remove the confidential and unnecessary elements, and give us a compilable example (including a main() function, a simple class, and an output display) that demonstrates the problem. Otherwise, it's difficult to understand the problem.
@sneubert just saw the license from poppler and i want to use a PDF viewer with LGPLV3 like QtLabs PDF module instead, so i think i will go on from there but thanks for your help
Hi and welcome to devnet,
AFAIK, the recent version of the QtWebView module uses the QtWebEngine module for Windows. Module that is not available for MinGW currently. Also you are are using a relatively old version of Qt so first thing you should update if possible to at least 5.8.
@Devopia53 I tested on Qt 5.8/Win7 today. The same incorrect result. But today i discovered the difference in overlaping behavior on my two machines. On the machine with video card fully-transparent widget has black color on white opengl context :D, where as other machine with integrated video card has no color(as should). So the gui transparency on opengl context is very platform dependent. Solution is to render widget by opengl directly but this way is very inconvenient. I think troll-tech must solve this problem in future.
@FrankiPL
I suspect @speeter will have long disappeared, as that post was a year ago :)
Just a thought: have a look at (the first part of) https://raspberrypi.stackexchange.com/a/61086, which claims it's a generic Linux problem rather than just a RPi one. It's not quite the same messages, but worth investigating?
Hi and welcome to devnet,
Glad you found out and thanks for sharing.
Since you have ti working now please mark the thread as solved using the "Topic Tools" button so that other forum uses may know a solution has been found :)
@Mandar-Khire If you change your basic C++ program like this then you will not see the output as well:
#include <iostream>
using namespace std;
int main()
{
cout << "Hello World by C++!";
while(true);
return 0;
}
Qt uses an event loop, so after executing
void Widget::on_showButton_clicked()
{
cout << "Hello World by QT!";
}
your program is "sleeping" in the event loop and not flashing cout buffer.
I was having this same problem, turns out I was restarting too soon. The file transfer was so slow that took over a minute to transfer a 2Mb file.
I still don't have a good solution, I am using system("cp file1 file2") for Linux as a workaround, but don't have any suggestions for a portable solution.
Hi
You mean for the creation of the files or
what do you mean with
"manage the documentation in all platforms"
I just use word and have 1 doc for each language.
Not fancy and also looking for better way as its hard to keep track
of status of the various languages when new text is added.
