Qt Creator not showing.ui 在运行时发生变化

Question

Similar to this question: Qt Creator: Design changes not showing when run

I cannot make a simple change in the UI and then see it when I run. I've tried adding a dummy label and push button. No matter how much I edit the MainWindow.ui file, I can not get the UI to change. The ui_MainWindow.h file also does not change. It seems like whatever is supposed to generate that file is not being run.

I've tried cleaning before I run. I've tried unchecking the 'Shadow build' option under Projects >> Build & Run >> General >> Shadow build checkbox and then restarting Qt Creator. I've tried restarting my PC and then testing. That damn ui_xxx file will not update!

Host OS: Windows 7, 64b Qt Creator version: 3.0.1 based on QT 5.2.1 (MSVC 2010, 32 bit), built on Jan 31 2014

Answer 1

One reason for this buggy behavior is the Shadow build checkbox is enabled. Click on the "Project" icon in the Qt creator, under Build-> General, uncheck Shadow build. Rebuild again and run.

Answer 2

After modifying UI elements on a project what worked for me was to delete the directory: {project dir}/GeneratedFiles followed by a project rebuild.

UI elements including menu changes seem to work after deleting. I tried the clean followed by rebuild, including unchecking the shadow build.

Qt Creator 4.11.0

Answer 3

Just had the same issue. Delete (or at least put it somewhere else) the ui_*.h file, and recompile the program. It fixed for me.

Answer 4

sk313tOn is correct. For shadow-build delete ui_mainwindow.h in your project directory. Because for shadow-build the correct location of ui_mainwindow.h is the build directory. ui_mainwindow.h will be build in the build directory automatically.
