[SOLVED] Removing .ui form leads to segmentation fault

nanthiran_2005

HI all,

I' trying to remove the .ui form and all its associates pointer from the .h and .cpp file. After removing them, I ran qmake and rebuild the project. However, when I Run the project, the program end unexpectedly. I tried debugging by putting breakpoints, but it did not even enter the main function.

Am I missing any step in removing the ui file? Thanks in advance.

Hi,

You should rather delete your build directory when doing that.

Hi,

Remove the .ui name from the * .pro* file.

Ex: FORMS +=
topmenu.ui
welcomescreen.ui
inputrecordrange.ui
inputtabularrange.ui
about.ui

in above case if you have deleted about.ui & inputrecordrange.ui, you just remove the names from FORMS

FORMS +=
topmenu.ui
welcomescreen.ui
inputtabularrange.ui

Hi,

Thanks SGaist. Deleting the whole build directory helped me to solve that problem. And yes Pradeep, I did removed the .ui file before too. But that alone didn't help.

One thing to note though; after deleting the build directory, I still had segmentation fault which is caused by the code below:

@QHBoxLayout *layout = new QHBoxLayout;
this->centralWidget()->setLayout(layout);
@

So I changed it to this:

@QHBoxLayout layout = new QHBoxLayout;
QWidget w = new QWidget;
w->setLayout(layout);
this->setCentralWidget(w);
@

You're welcome !

By default there's no central widget, hence the crash.

So I believe the code didn't crash when I was initially using the form as the form provides a default central widget.

SGaist

You're right

Since you have it working now, please update the thread title prepending [solved] so other forum users may know a solution has been found :)
