I'm using Qt Creator.
I'm using the signals and slots editor, and I want to see the code it generates.
How can I see the code?
Thanks!
Let's say you have in Qt Creator a form file called widget.ui.
Once you've compiled your project, you'll find in your project folder a filed called ui_widget.h.
If you open it, you'll see the code generated by the uic tool.
when you use qt creater, this one is going to create a file with the name of your project, in my case it is called "build-prueba-Desktop_Qt_5_7_0_GCC_64bit-Debug", then in that file you have to look for a file with the "ui_" prefix, into that, you have the code you need

I have started to develop an app using Qt Creator, and I am dealing with signals and slots. The problem I have is that I have no way to figure out how to view the code generated from my .ui file I am building. I want to edit some signals and slots but I can't do more than the GUI stuff. Is there a way to view all the source code that is generated when I build my .ui file in creator, or do I have to use another part of the Qt suite?
The .ui file is fed to uic to generate .ui.h file. You should be including that file in your code. Place the cursor over the name of the include file within the #include "foo.ui.h" line, and press F2 to see the contents of the file.
There is no other output from a .ui file. "Qt", specifically the Makefile for your project, doesn't generate anything besides a .ui.h file.
I have a Qt project in Qt Creator. I have a qrc file with the QMLs registered and everything works. However for some reason the "projects" view of Qt Creator doesn't show the QML folder (screenshot attached) like it does for any example project.
I'm just curious. Why does QML folder not show in my project but it shows up for the example projects?
You need to add them to your .pro file (if I'm not wrong it's enough to append them to DISTFILES).
Figures that you have to add the files to the DISTFILES directive.
My Qt project uses shadow build.
When I change in MainWindow form ( .ui file), I build the project but my program doesn't update GUI.
If I rebuild all, GUI will be updated. But rebuild is very very slow.
I try creating a new project (an empty QMainWindow with some labels), I modify some texts. I build and GUI is updated.
How can I use shadow build correctly, without a rebuild of all my project?
The same issue occurs if the *.ui file name is changed.
For example, Changing yourUi.ui to myUi.ui.
If that is the scenario, then the ui_*.h should also be changed, that is, yourUi.ui to ui_myUi.h.
close Qt creator, go to your project directory and delete the .pro.user file, open the project again and this time Qt creator will ask you to configure your project by choosing the kit you use to build your project. Select the appropriate kit and press the "configure project" button. Apply your shadow build. I hope it will work.
Have you tried to just run qmake (Build -> Run qmake) ?
Edit
As suggested by a comment, I copied the comment to preserve it.
It seems that QtCreator correctly rebuild the .h file of the ui in the shadow build directory, and then include the ones in the source directory, which is not regenerated. I don't know if this is a bug or an intended behaviour, but a quick workaround can be to build the project in the shadow build directory, copy the generated .h files back in the source directory and rebuild again. This work with my simple project, don't know if can be workable also for bigger and more complex project. Or do not use shadow builds
I am new in Qt framework and now, I want to create an app which supports multi-language display. I known there is a way to do: Qt Linguist. I searched, and archieved some information about lupdate, lrelease ... But I just have Qt Creator IDE, how can I run or compile lupdate, lrelease ???
How can I create *.ts file ?
Please give me some code example or guide to do. (I often use Qt Designer to create GUI)
As far as i know, there is no option in QtCreator to use QtLinguist - you have to do it manually. Here you have an excellent documentation about how to do it. I have learned from there also.
I want to create a gui, if it means implementing the code, where do I implement the code? And how to run the qtdesigener?
You can use Qt Designer, or Qt Creator which is a full developement environment (IDE) not just a GUI designer. Visit this site http://qt.nokia.com/products/developer-tools
Each window or widget in Qt generally is defined in 3 files:
some_name.ui - this file is generated by Qt Designer or Qt creator.
some_name.h - this is the C++ header file that contains Class declaration
some_name.cpp - this file contains C++ class implementation
some_name ofourse is the name of your widget/window.
When You add new windows/widgets to your Qt project you have to modify Your *.pro file which contains information on how to build your project.
The following tutorial shows a hello world in qt creator:

I hope this is what you were looking for.
