The rationale is that the designer can break these connections without any warning. Eg if you cut and paste some widgets to move them around, any connections to those will be silently broken. It's much safer to rely on manual connections with compile time checks...

[QGIS-Developer] Signals and QtDesigner (2)
Hi again, sorry but I have a idea... I compiled QGIS and realized that signals connections made with QtDesigner are compiled into old style signal-slot connection: QObject::connect(mCustomDelimiterOption, SIGNAL(toggled(bool)), mCustomDelimiterText, SLOT(setEnabled(bool))); What is also forbidden by QEP #77. So I guess this answers my question. Thanks a lot anyway.

[QGIS-Developer] Signals and QtDesigner
Hello all, I write the list because I have a a simple question (currently I'm trying to tackle issue #56275 Improve Parsing of Data from Serial Port Sensors). Is using the QtDesigner signal/slot assignment facilities discouraged? I've read this in the QGIS coding standards guide and don't really know if that means that: *Avoid use of Qt auto connect slots (i.e. those named void on_mSpinBox_valueChanged).* So, If I need to connect two widgets in a groupBox (a radioButton and a QLineEdit, just to enable the QLineEdit only a determinate radioButton is selected), should I make it programatically instead using QtDesigner?

[QGIS-Developer] Qt6 python plugins: visual hint in PluginManager plugin list?
Hi, Maybe it is a little too early, as not so many people will be able to test Qt6 builds of QGIS? But I have one :-) And I upgraded a first plugin that is working both in Qt5 and Qt6 [0] Now I'm wondering if there should be some visual cue, when working with a Qt6 build, when searching for plugins. 99.9% of the plugins will not work :-( And pop up the attached screenshot. Any idea's on how to handle this user friendly? Hiding the Qt5 plugins does not seem a good idea (to me). Maybe 'graying' out all plugins that do not have `supportsQt6=yes` in their metadata is easiest, and would maybe users ask for Qt6 upgrades to plugin authors? Alternative would be some checkbox/filter for Qt5/Qt6 plugins/ Other idea's, or should we/I just not bother?
