QT Creator keeps crashing when run

[jakemaggieronan]

I have a project using QTabWidget that crashes most times I try to run it. I have some output from debugger mode below. I am not sure what the issue is as I have not touched the code related to QWidget/QTabWidget, and I have reverted back to a commit that I marked as "working" in the past (I know this is sus but I trust myself and it seems like this issue started happening independent of code changes. or accumulated somehow, like a memory leak?)

I have restarted my machine just in case, still crashes. Any thoughts about what I can change to stop this crash from happening? It's preventing dev work. Thanks. The debugger arrow comes out on the bolded line about QTabWidget.

// groupings by project
QWidget *brushGroup = new QWidget();
QVBoxLayout *brushLayout = new QVBoxLayout();
brushLayout->setAlignment(Qt::AlignTop);
brushGroup->setLayout(brushLayout);

QWidget *filterGroup = new QWidget();
QVBoxLayout *filterLayout = new QVBoxLayout();
filterLayout->setAlignment(Qt::AlignTop);
filterGroup->setLayout(filterLayout);

QScrollArea *controlsScroll = new QScrollArea();
**QTabWidget *tabs = new QTabWidget();**
controlsScroll->setWidget(tabs);
controlsScroll->setWidgetResizable(true);

tabs->addTab(brushGroup, "Brush");
tabs->addTab(filterGroup, "Filter");

vLayout->addWidget(controlsScroll);

// brush selection
addHeading(brushLayout, "Brush");
addRadioButton(brushLayout, "Constant", settings.brushType == BRUSH_CONSTANT, [this]{ setBrushType(BRUSH_CONSTANT); });
addRadioButton(brushLayout, "Linear", settings.brushType == BRUSH_LINEAR, [this]{ setBrushType(BRUSH_LINEAR); });
addRadioButton(brushLayout, "Quadratic", settings.brushType == BRUSH_QUADRATIC, [this]{ setBrushType(BRUSH_QUADRATIC); });
addRadioButton(brushLayout, "Smudge", settings.brushType == BRUSH_SMUDGE, [this]{ setBrushType(BRUSH_SMUDGE); });

// brush parameters
addSpinBox(brushLayout, "red", 0, 255, 1, settings.brushColor.r, [this](int value){ setUIntVal(settings.brushColor.r, value); });

@jakemaggieronan Your app is crashing, not QtCreator, right?

[jakemaggieronan]

@jsulm yep it's the app :/

Hi,

Nothing obvious stands out from your code. One thing you can do is comment out everything and add back elements one after the other until the crash occurs again.

[jakemaggieronan]

@SGaist Thanks, I was able to fix the issue (as in, the crash stopped happening) by editing some code in a different file. I had been confusing two data structures and using them interchangeably, causing errors. I am new at this, clearly. Thanks.

@jakemaggieronan glad you found out and thanks for the feed back !
Please mark the thread as solved since all is working now.
