12/13/2023 0 Comments Qt creator signal slot editor![]() QObject::connect: No such signal QCustomPlot::rangeChanged() in. In QT Creator while run the appa this message appear, Warnings(?) Only the command connect is nedded?, of work in union with the ui Edit signal /slots editor, or both do the same? Honestly I dont understand very well of do this connections, the tutorials are ambiguos. I use the customwiget in my project only by including the header in the mainwindow header file. To do that, you can press the F4 key, select the Edit>Edit Signals/Slots option in the main menu, or click on the Edit Signals/Slots button on the toolbar. My app has many custom widgets each has their own signals, but I need one of these customwidget control the other other ones, the tutorials always use qt creator with included widgets, when I use the Edit signal /slots editor, in the end the IDE seeks the signal function of the customwidget in the mainwindow, when this signal is defined in the own file of the customwidget, I dont know then of connect the customwidgets. To establish a signal and slot connection between two widgets in a dialog, you first need to switch to Qt Designer's Edit Signals/Slots mode. ![]()
