Qt Meta Object Compiler Install Adobe

Disclaimer: I'm not an avid Qt Creator user, so I may be wrong. If Qt Creator supports custom compilers, try setting the mingw compiler as one, and setting the library paths to mingw's include directories (along with the appropriate paths for the windows headers). This method has worked for me in the past on other IDEs (such as codeblocks), so I'm going on a limb and guessing it will for Qt Creator as well.

The documentation on Qt is very. What is Q_OBJECT macro and what is the need of. Slot concept and with that macro you need to run meta object compiler. Qt cannot find compiler. Qt employs a MOC - a meta object compiler. While installing it did not ask to install GCC or any other compiler.

Edit: After doing some searching around in Qt Creator, I'm not too sure if this is possible.

Qt Meta Object

Hello and welcome to devnet! You use the QOBJECT macro to tell the compiler that this class uses own signals and slots. AFAIK Qt doesn't use standard signal & slot concept and with that macro you need to run meta object compiler (moc) first - it changes the code in 'real' c code that is usefull for the g compiler.

Hence, you write it in the classes you define to have own signals & slots and then you pre-compile it with moc and finally compile both (mocfile.cpp & file.cpp). (I hope that is correct like this^^). Hi, I hate to be the one to tell you to read the documentation. The documentation on Qt is very good, for that question look at 'QObject': So to answer 'when we need it', in there you get the following: Notice that the QOBJECT macro is mandatory for any object that implements signals, slots or properties.

You also need to run the Meta Object Compiler on the source file. We strongly recommend the use of this macro in all subclasses of QObject regardless of whether or not they actually use signals, slots and properties, since failure to do so may lead certain functions to exhibit strange behavior. And to expand that a bit, for everything that inherits from QObject:).
