Description:

QLed is a Led custom widget plugin for Qt Designer 4.x
It requires Qt library 4.x

It allows to choose among Circle, Square, Triangle, RoundRect shapes and also allows to choose among Red,Green,Yellow,Orange,Purple,Blue on-colors. Off color is Grey.

Version 0.5.0 beta

This version is beta, I'm working on the source code to improve it and to add new shapes.

 Plugin not added

 
 by EL91 on: Nov 24 2015
 
Score 50%

Hi,
I downloaded the plugin and followed the INSTALL instructions. Every instruction worked successfully. The problem is, when I open QtCreator, I don't find QLed in the Designer.

By the way, after installing the plugin, "qledplugin.prl" and "libqledplugin.a" files are generated in my Qt\plugin\designer folder. ( No dll generated).

Please help me
