qDebug() << ui->textEdit_40->objectName() << ui->textEdit_41->objectName();
qDebug() << ui->textEdit_40->objectName();
qDebug() << ui->textEdit_41->objectName();

all caused crash, no messages, that i found

Hi,

Is ui initialized properly ?

[JonB]

@micha_eleric
So it looks like you have a problem with those two textEdit pointers? Btw you have done a clean rebuild, so the uic has been run on the latest .ui file? You have initialised the ui prior to this code?

At one point you said a SIGSTOP was reported. Now you talk about "crashing", or just exiting. In any case, are you compiling for debug and running inside the debugger? Does the debugger catch anything/stop/report anything when your code goes wrong or exits?

if i dont compile for debug, it runs, till i get to code that crashes. compile debug, and it crashes before getting to error code, and tells me nothing about where.

actually, i am using a .h file. just saw yesterday, that i could not open it with qt 5 designer, and qt 5 designer saves in .ui

most other text boxes and buttons run fine.
code in .h file for text boxes and buttons, look like copy/paste except numbers change.
dont know how to convert .h to .ui, or how to open .h with qt 5 designer. the qt designer i used before was much easier to design with.

I happen to notice that after ui->textEdit_38 ui->textEdit_39 is absent, then you say it goes wrong at ui->textEdit_40. Don't know what you want 40+ text edits for, but anyway why not delete all after ui->textEdit_38, make sure it works at that point. Then add the further ones in and see how it goes.

yah. not sure about that.
did find 39,40, and 41 cause a crash in another part that call those three, but not the other text boxes.

runs fine

           std::cout << "InitTestBoard try 3 \n" << std::flush;
         //   ui->textEdit_40->setFixedSize(30,  30);
         //   ui->textEdit_41->setFixedSize(30,  30);
            ui->textEdit_42->setFixedSize(30,  30);
            ui->textEdit_43->setFixedSize(30,  30);
            ui->textEdit_44->setFixedSize(30,  30);
            ui->textEdit_45->setFixedSize(30,  30);
            std::cout << "InitTestBoard try end \n" << std::flush;

crashes

            std::cout << "InitTestBoard try 3 \n" << std::flush;
            ui->textEdit_40->setFixedSize(30,  30);

            ui->textEdit_45->setFixedSize(30,  30);
            std::cout << "InitTestBoard try end \n" << std::flush;

found it
in CUi_MainWindow.h [the file that has gui layout] file 39, 40, and 41 are different

@micha_eleric
Do a complete project rebuild/make some change in Designer to update the .ui file and force uic to run on it again. ui_MainWindow.h is a generated file; don't change it yourself, it will get overwritten.

[micha_eleric]

@JonB not sure where to ui or uic files are. if i still have them

[Pl45m4]

@micha_eleric

uic is the User Interface Compiler, which does exactly what you've mentioned before.. creates an usable header from your *.ui design template...
And every time you re-run it, your header file will be created or updated... so it makes no sense to edit the file yourself and change some object names

[micha_eleric]

@Pl45m4 just found the .iu file.
trying to remember what i did 4 years ago

@micha_eleric
Go into Designer, make some small change, save, build, does it work now?

[micha_eleric]

@JonB build is gray

[micha_eleric]

@JonB ok. default opens with qt creator, and build is gray
open with qt designer, and find no build

where is build in qt designer?

There is no build in QtDesigner.
You build your project in QtCreator. And you also should rather edit ui files in QtCreator (QtDesigner is integrated there)...
