3rd Party Software

Hi Hilk,

Thanks for your answer. I already what you suggest, the problem is how how to pair with the device. This is already working on Linux I thought I may be doing something wrong

Hi,

It usually depends on how the library itself works. You can queue "commands" you want the library to execute and your thread can execute them one after the other, or you can use QtConcurrent which is higher level thread management.

Hi VRonin,

Thank you a lot, that works perfectly!!!

@bhargav said in How to use matlab mspeaks predefined functions in Qt?:

how to use matlab library function in Qt and give me clear info if any one know.

@srav219

Not sure if here users with enough experience are around.

It might be good also to post on android-qt onGoogle.

@LeLev
sry, but how is this Qt related at all?
Beside that you use Qt in other parts of your application.

Nor do you even post a stack-trace of the crash...

Since this has little to nothing to do with Qt, you should probably ask the author directly: https://github.com/OpenGP/starlab/issues

P.S.
You seem like you are trying to use Qt4 while the library is for Qt5

@VRonin
Ooo, I'm glad my company doesn't look like that!
I wonder if now would be a good time to invest in some Qt Company shares? ;-)

Hi,

As @VRonin already suggested, as QtRPT is not an official Qt module, you should contact the author of that module to get more information about it.

@jalal_ba you're using OpenCV 3.4 and the guide you referred is using OpenCV 3.2 could it be possible you try with the old version to see what happens?
In addition, the error you have is related to Google protobuf, so you may want to check this issue regarding OpenCV and protobuf under Windows.

Assuming you want to show on the screen in the tableview.

In this example I used QStandardItemModel:

QXlsx::Document excel(filename); int row=excel.dimension().firstRow(); while(row != excel.dimension().lastRow()) { mModel->setRowCount(excel.dimension().rowCount()); mModel->setColumnCount(excel.dimension().columnCount()); for(int col=0; col < excel.dimension().columnCount(); ++col) { setValueAt(row, col, excel.read(row, col).value<QString>()); } ++row; } void QExcelView::setValueAt(int row, int col, const QString &value) { if(!mModel->item(row,col)) mModel->setItem(row, col, new QStandardItem(value)); else mModel->item(row, col)->setText(value); }

QuaZipFile is a file inside the zip, not the zip file itself

See https://stackoverflow.com/questions/2598117/zipping-a-folder-file-using-qt/2598649#2598649 for an example (in outFile.open() you'll have to pass 3 more arguments, all of them 0 to have no compression) or use the easier, more maintained KArchive library instead

Something like nlog for QT/C++ ? I found log4cplus. I would like to log async, change log configuration at runtime and redirect log output to a remote macine when needed.

Hi,

That's something you should ask directly to the project author.
