How to remove manually created form and replace with QTDesigner creatted one.

Please give me some credit - just because I do not spell / say I complied it does not mean I did not.

I have no idea what you mean. All I have done is try to explain things. I have not "failed to give you credit" for anything at any stage. If you're not happy with the explanation we can leave it, but I'm not going to be told I have not given you credit or been anything other than helpful and polite.

You haven't answered the question I gave you about #1 versus #2, so I am non the wiser as to where your phrasing of "why my change in the actual l form did not take?" refers to. Nor what your "I exit the QTDesigner and go back to QTCreator" means --- I can't tell whether you are in Creator the whole time and use Designer in one of its windows, or whether you go outside Creator and run up a separate Designer instance.

Please note the button text in lower right corner .

How do I find WHICH whatever file (device ??? ) is run ?

When you create a form in Designer (that's the word it uses for a "visual widget you design") you might call it form or device or banana. Let's say it's banana. Then:

The Designer file for the form (visual widgets) will be banana.ui.

When uic banana.ui gets run it will produce a file named ui_banana.h.

How do I verify
a. If `uic " runs at all ?
is there verbatim output available ?
(can i read the date of creation of NEW ui_deviice.h - where ?)
b. It appears that there are at lest TWO "device.ui" - therefore which one is being run - by "uic" ?

You will also have files banana.cpp and banana.h, which you can edit for your own code.

That would defeat the GUI of QTDesigner....

banana.cpp will have a #include "ui_banana.h" line and a #include "banana.h" line.

That looks as an answer to above "date of creation " question.

So if (?) "device.ui" is read - why my change in the actual l form did not take?

Maybe when you answer questions in my previous post about what you might mean by "I exit the QTDesigner and go back to QTCreator only to find out ..." we may know.

PLEASE ..... get real....

man ls is your friend. Or a simple file manager which is able to show the creation date (so I would say all of them).

b. It appears that there are at lest TWO "device.ui" - therefore which one is being run - by "uic" ?

There is only one in a build directory, otherwise you should clear you build dir and start over. Also the generated file must not be in your source dir - maybe you copied it by accident in there.

Told you what there is. You're wrong if you think/believe otherwise.

b. It appears that there are at lest TWO "device.ui" - therefore which one is being run - by "uic" ?

Hence your issue, as suspected.

PLEASE ..... get real....

Pardon? You're not wishing to be insulting again are you?

QTCreator does same

'
it is source directory and I did not put it there .

It is same as when I use QTCreator to build dialog project and it works / updates just fine.

All good points...'

Now let's answer this - used as a troubleshooting aid
I added "go to slot " by pressing the button on the form in question
it works as expected

my conclusion
the form was saved / updated/ complied /uic and processed correctly

so WHY same is not happening when text of the button is changed ?

what is the difference ?

I have deleted existing references ( include ) to my ui_device .h .
Run "clear" AND "rebuild" .

It failed with multiple errors .....

If file "ui_device.h " is "produced" - where is it ?
It seems logical the compiler has to be made aware of it - using "include ".
Is there any other way to make sure it is being created ?

You will also have files banana.cpp and banana.h, which you can edit for your own code.

banana.cpp will have a #include "ui_banana.h" line and a #include "banana.h" line.

Your ui_device.h should be being produced in the "build output directory", for which ever configuration *debug, release, ...) you are building for. Cannot say for sure where yours is, depends on your configuration settings. I often put mine in a difference place. If you are using the default I think you go to the parent of the directory containing your source files and look for a directory named something like build-projectname-debug.... Your compiler's .o files are there, as is your executable.

If you have a ui_....h file in the same directory as your source files (where the ....ui file is), that is bad, try deleting it.

Do not delete your .ui files though till you are sure what is going on! Keep a backup copy.

I have deleted existing references ( include ) to my ui_device .h .

If you remove the #include "ui_device.h" line from your device.cpp file it will not compile. ui_device.h holds the C++ generated from the .ui, and your device.cpp will likely be making lots of references to its content.

The discussion will not resolve the issue by repeating the same...

Now let's answer this riddle

used as a troubleshooting aid-

I added "go to slot " function in QTDesigner (file) activated by "pressing the button" on the form in question. It shows in QTCreator in all usual places without any additional need for verification of any of the files involved.

it works as expected

my conclusion
the file / form was saved / updated/ complied /uic etc. and processed correctly

so WHY same is not happening when text of the button is changed ?

what is the difference ?

ADDENDUM (APR 30)
AFTER a source files are renamed and project is saved / rebuild , then the
"created " ui_device.h file STILL refers to the original "device.ui" which no longer exist.

speculation:

either uic is bogus or the original file is still used ( most likely ).

Christian Ehrlicher

As already said - you most likely have another generated file somewhere in your compiler search path - you're doing a lot of strange things so this is the most likely version.
Remove all occurrences of ui_*.h and compile your application. Then this file is re-generated and used by the compiler.
Neither QtCreator nor the compiler can do anything against your strange way copying data around...

The discussion will not be resolved by not acting on what we try to tell you repeatedly!

What have you done about:

If you have a ui_....h file in the same directory as your source files (where the ....ui file is), that is bad, try deleting it.

?

b. It appears that there are at lest TWO "device.ui" - therefore which one is being run - by "uic" ?

There cannot be two files named device.ui in the same directory. So they must presumably be in different directories.

If you want to know which one where is being written to by Designer, make a change in Designer, save, and look at the file modification time on each of the .ui files.
If you want to know which one is being read by uic, temporarily rename/move the .ui files one at a time, which one causes the build to complain?
If you want to know where/when uic is putting the ui_....h file it generates from the .ui, remove all ui_....h files from source and build output directories, rebuild, and see where it appears.

I have renamed the only occurrence of ui_device.h - in source folder.

Here is the compiler result building ONLY the btscanner project :

Does this verify that there is only one , in this case nonexistent , ui_deviuce .h" file ?

Should I rebuild the ENTIRE project ?

BTW
Another anomaly
during project compile I get flash of real error , as expected, but then the error message is nowhere to be found in regular expected places.

PS
THe expected error shows up in "issues" when entire project is build

:-1: error: No rule to make target 'test_device.ui', needed by 'ui_test_device.h'. Stop.

I believe this exercise confirms that the ui_xxx file is NOT regenerated when changes to the "form" are made.

Now what ??

Neither QtCreator nor the compiler can do anything against your strange way copying data around...

@AnneRanch said in How to remove manually created form and replace with QTDesigner creatted one.:

make: *** No rule to make target 'test_device.ui', needed by 'ui_test_device.h'. Stop.

So is there actually a test_device.ui in /media/q5/MDI/QT_PROGRAMS/SOURCE/bluetooth/btscanner/ ? If not remove it from your pro-file and start over...

I have renamed the only occurrence of ui_device.h - in source folder.

Told you already more than ten times - the generated files must not be in your source directory...

I believe this exercise confirms that the ui_xxx file is NOT regenerated when changes to the "form" are made.

It tells you it is indeed trying to regenerate ui_test_device.h file from test_device.ui, by running uic on it, but it cannot find a source file test_device.ui. Has it always been like this, or is it because you have renamed/moved test_device.ui? Where is your test_device.ui file?

Your project build shows line:

WARNING: Failure to find: test_device.ui

As long as that and/or the other error are occurring, changes saved into the .ui file e.g. from Designer are not being reflected in your rebuilt executable.

So the exercise shows that the ui_xxx file IS TRYING TO BE regenerated when changes to the "form" are made
