Hi! I've installed my Qled plugin and already see Qled on QtCreator, but since I'm doing all my GUI on Python3, I'm converting my .ui files into .py with pyuic5. The problem is that after doing that and running my .py with my GUI with a Qled widget I'm getting "ImportError: No module named 'qled' Any idea what could be wrong or missing?

Hola buenas, quisiera saber como instalar este widget en linux! estoy trabajando en una raspberry pi!

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

qled 0.6.2 - plugin successfully built and used on OpenSuse 13.1. Anyway, i would prefer to use the Promotion technique and not create a plugin. ( http://qt-project.org/doc/qt-4.8/designer-using-custom-widgets.html#promoting-widgets ) Can i do this with qled ?

With a recent Qt, you can compile QLed into an app or static lib by removing QDESIGNER_WIDGET_EXPORT and the QtDesigner include from the QLed class definition.

I have been trying to get the qledplugin to be recognized by Qt 5.0.1, with no success. Anyone get this to work?

I've got the same problem as others compiling the project on ubuntu 10.4

I tried to install QLed to Qt 4.7 on WinXp using qmake qledplugin.pro. I got the following error message: --- Could not find mkspecs for your QMAKESPEC(win32-g++) after trying: C:\iwmake\build_vs2008_commercial_________________PADDING_______________ __\mkspecs Error processing project file: qledplugin.pro --- I don't understand the error and need some hints.

Hello, I have the same problem when add qLed in QtCreator: Win32: undefined reference to `_imp___ZN4QLedC1EP7QWidge` My paths are: C:\Qt\4.7.4\bin; C:\Qt\mingw\bin\; My QtDesigner see this qLed, I had added it to QtDesigner, but how to do that QtCreator understand it? What and where I need to copy for this?

I have spent the past few hours fighting with Qt and cannot for the life of me get this Signal/Slot pair connected. I can connect to the slots that don't use QLed enums, but the ones that do will not let me use them no matter what I try. Here is how I am connecting to the slot from my MainWindowImpl object: connect( this, SIGNAL( setLEDColor( QLed::ledColor ) ), cpux_ql_ProgramCPUX, SLOT( setOnColor( QLed::ledColor ) ) ); This is the error message I'm getting: Object::connect: No such slot QLed::setOnColor( QLed::ledColor ) Object::connect: (sender name: 'MainWindow') Object::connect: (receiver name: 'cpux_ql_ProgramCPUX') I am using Qt Designer to make my ui and I am using QDevelop for compiling. Does anyone have any suggestions?

I compile the qled app. When I try to include a qled in my project (I use vs2005 and qtDesigner) I obtain a list of errors like this one: "ERROR LNK2019: unresolved external symbol ... QLed::setShape(...". More specifically one of this errors for every function declared in the .h file. I had copy the dll file in "<QTDir>/lib" and in "<QTDir>/plugins/designer" Any one suggestion?? Thank you

i have compiled the qledplugin.dll and qledplugin.a（release version）.QT designer can use it, but qtcreator can not debug my app with the plugin. any solusion? some warning likesome thing "Redeclared without dllimport attribute after being referenced with dll linkage "

it seems like there is a memory leak in the code. every time you toggle the LED by clicking the checkbox in the example application new memory is allocated. I think this is because you create a QSvgRenderer at the beginning of the paintEvent method of QLed without freeing the memory at the end of the routine.

I enjoy doing my layouts in code, not using Designer. As soon as I #include "qled.h" I get .exe exited with code -1073741515 error. I want to include following: QLed *led = new QLed(); Please advise. Shaun

Dear I have little time testing QT. I installed QT 4.6, employment Creator QT 1.3.0, on Windows 2000 I compiled QLed, generating the debug version and release, I copied the release version qledplugin.dll in the C: \ Qt \ 2009.05 \ bin \ designer \ I created a new project with a form, I tried to load the plugin via the menu Tools -> Form Editor -> About Qt designer plugins. Plugin Information on the form, sample; Failed Plugins c: / Qt/2009.05/bin/designer/qledplugin.dll The add 'C: / Qt/2009.05/bin/designer/qledplugin.dll "uses incompatible Qt library. It was hoped the key "Windows msvc release full-config", but received "Windows mingw release full-config" To load the plugin in Qt Designer as a control, as I act? I suppose that when you load a dll plugin, this should appear as a more, like for example a combo box, label, .... And I just need to drag the control on my new form to dispose of the object, is this so? Why the error?, How can I solve? Thank you

How can I add this plug-in to qt-designer, I tried nmake but got some error messages, is there any other way to add plug-ins.
