Description
Navigating the Issue list in compiler errors with the Up/Down keys is completely broken in Qt Creator.
- It highlights the wrong line
- It jumps between errors (e.g. pressing Down 3 times goes to error A, C, B instead of A, B, C)
It is really, really broken. It makes developing C++ with QtCreator a nightmare, almost unsuable.
The following code can repro the errors:
#include <stddef.h> #include <stdint.h> void foo( int a ); void foo( int a, int b ); void foo( float c ); int main() { unsigned int a = -1.0f; foo( "hello" ); foo( "hello" ); unsigned int b = -1.0f; foo( "hello" ); unsigned int c = -1.0f; foo( "hello" ); return 0; }
See attached movie. I'm just pressing 7x Down 7x Up. It does whatever it wants.
Update
Looking at the changes, it is possible the bug is caused by a race condition.
- I'm using Ninja Generator (not GNU Make)
- I have a Ryzen 5900X, so I have 24 threads
- I use Clang++-12
Small update:
- QtCreator 7.0 is also affected
- QtCreator 6.0.2 is NOT affected
Small update 3:
I tracked the bug to src/plugins/projectexplorer/taskwindow.cpp:
const bool selected = view->selectionModel()->isSelected(index); const bool current = view->selectionModel()->currentIndex() == index;
When changed to:
//const bool selected = view->selectionModel()->isSelected(index); const bool current = view->selectionModel()->currentIndex() == index; const bool selected = current;
Everything backs to a working state.
Something I noticed is that according to the bug tickets QTCREATORBUG-25547 & QTCREATORBUG-26720 this new feature is supposed to allow multiple selections (i.e. via Shift + Click or Shift + Arrow). However on Linux, it doesn't seem such feature is working at all. I can only select one issue at a time.
BISECTED!
