QWT Widgets not showing Qt Designer

SGaist

What does the about box of Qt Creator tell you about the Qt version used to build Qt Creator ? That's important piece, you have to build the plugin using that version of Qt,

@SGaist Qt Creator 8.0.0 based on Qt 6.3.1. But ım using desktop Qt 5.15.2 MinGW 64-bit. Thats mean when ı build new project ım use Qt5.15.2 MinGW . İts enough for you ? Thank you sir.

@horizonQt If you want to build a plug-in for QtCreator you have to use same Qt version which was used to build QtCreator. So, build it using Qt 6.3.1

im using qt creator 8.0.0 based on Qt 6.3.1. ı want to add qwt6.1.6 widgets on designer. Can you explain step by step what not to do?

@horizonQt See "Qwt and the Qt tool chain" -> "Designer plugin" in https://qwt.sourceforge.io/qwtinstall.html"

@jsulm I followed the steps. but it still does not appear as a widget. I can add it as a library and create a gui as hardcode. but ı dont see widget at qt designer

jsulm

@horizonQt Was the designer plug-in build and installed?
If so you can debug plug-in issues by setting QT_DEBUG_PLUGINS to 1 before starting QtCreator (in a terminal) - that should give you more information about plug-in loading issues.

@jsulm ı cant see any problem application output. Where should I look, what should I look for?

As I wrote in the terminal where you set QT_DEBUG_PLUGINS and start QtCreator
