QUESTION
I want to embed the python script in my c++ Qt application, By searching on the net I found that PythonQt is exactly what I am looking for but when I went to it's github repo there is build description given for windows system but not for ubuntu system so after cloning the repo if I include it's src in my Qt .pro file it gives me output that
Python.h not found, I think the reason is that I didn't build it in my system. Is there anyone who could tell me that how to build PythonQt in ubuntu. The link for their repo is this: https://github.com/MeVisLab/pythonqt
If this didn't work you can also suggest me some other thing which will help me to embed python scripts into my Qt c++ application.
ANSWER
Answered 2021-Jan-27 at 18:43First clone the repo by using the following command
https://github.com/MeVisLab/pythonqt.git
After that cd into the clone folder and execute the below command to build it into your system.
QUESTION
So, I am converting my project from qmake to cmake, and I'm just about done! However, I'm getting more than double the runtime speed on my qmake build, at least in debug mode. I'd like to have the same compile flags set in both build configurations so that I'm comparing apples to apples.
Unfortunately, I haven't had much luck figuring out what the heck is accounting for the performance difference! My qmake flags resolve out to this:

Answered 2020-Dec-28 at 05:30I figured it out!! cmake was building my application as a console app, instead of a Windows app. Replacing add_executable(${TARGET_NAME} ${MY_SOURCES}) with add_executable(${TARGET_NAME} WIN32 ${MY_SOURCES}) in my cmake build makes the performance match. I learned something new today, thanks all.

QUESTION
I'm working on an IDE for debugging scripts and codes in Qt my duty is to implement GUI and there is a very good example of Code Editor in Qt Documentation in this url: http://doc.qt.io/qt-5/qtwidgets-widgets-codeeditor-example.html
all of the introduced features (like line number and highlighting and syntaxes) are good explained but there are some words about implementing break point as an extension to the Code Editor documentation says:
In addition to line numbers, you can add more to the extra area, for instance, break points.
I just wondered since the document explicitly stated that a break point implementation would be the next step of developing a code editor component but as I googled and searched web sites I didn't find any relevant article or project with the related implementation or an example of implementing breakpoints into an IDE. I just wanted to ask if you know any example or guide about this matter I would be very glad if you can help me through this or otherwise I would sub-class and implement it by myself and ask much more detailed questions here.
thanks in advance for reading :)
UPDATE
I end up implementing such a features like : breakpoint and breakpoint area, current line that is running, step over, step in, continue and other debugger features and I used PythonQt as the API for communicating with Python/C API to debug my scripts from. I used QTextBlockUserData to implement the breakpoint data and it's aspects so it'll be managed by the block's data itself. that was all the things I was searching for in the first place. if anyone had any question I'd be happy to help.

Answered 2018-Aug-07 at 15:10My best guess would be to check out the QtCreator breakpoint support.
The UI part is contained in this class and others:
https://github.com/qt-creator/qt-creator/blob/master/src/plugins/debugger/breakhandler.cpp
... while the real logic depends on the engine. There are different debugger engines like gdb, cdb for Windows, QML debugger etc.).
Looking at the gdb engine, there is a gdb process running in MI mode. This mode makes it easy for programs to parse gdb output; try e.g. gdb -i=mi programToDebug. Also, the documentation might help: ftp://ftp.gnu.org/old-gnu/Manuals/gdb/html_node/gdb_211.html.
Qt Creator is then reading the gdb process' output to display information like call stacks; see e.g. https://github.com/qt-creator/qt-creator/blob/master/src/plugins/debugger/gdb/gdbengine.cpp#L244
So what I would do is this:
- implement UI to set breakpoints, start debugger etc.
- run debugger in an own process and machine mode (if available)
- connect input / output of that process to set breakpoints, display call stack etc.
QUESTION
in C++ BoolResult is casted to a pointer:
...ANSWER
Answered 2018-Feb-25 at 05:28The problem in your case is that you must assign appropriate values and you should not use None, for example if we see the docs of Qt:
int QInputDialog::getInt(QWidget *parent, const QString &title, const QString &label, int value = 0, int min = -2147483647, int max = 2147483647, int step = 1, bool *ok = Q_NULLPTR, Qt::WindowFlags flags = Qt::WindowFlags())
so a possible solution is to copy these values:
