Bug ID: 443415
Summary: Signals of IProjectBuilder cannot be connected
Product: kdevelop
Version: 5.5.0
Platform: Other
OS: All
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kdevelop-bugs-n...@kde.org
Reporter: kde2...@warship.prima.de
Target Milestone: ---
The signals of IProjectBuilder cannot be connected. I think the class must be
derived from QObject.
STEPS TO REPRODUCE
void TestView::built(KDevelop::ProjectBaseItem*);
void TestView::addTestSuite(ITestSuite* suite)
{
auto builder = suite->project()->buildSystemManager()->builder();
connect(builder, &KDevelop::IProjectBuilder::built, this,
&TestView::built);
OBSERVED RESULT
