Load a class and pass arguments to the constructor [Question]

[mayman99]

I've an architecture where I've the plugins has to have arguments passed to its constructors,

sth like this AuthorPlugin::AuthorPlugin(QWidget* parent) : SetupAssistantWidget(parent) and the SetupAssistantWidget is the interface, is there a way to do that with pluginlib?

[mikaelarguedas]

It is currently not possible to pass constructor arguments to plugins loaded by pluginlib (this is a restriction of class_loader the mechanism used for loading and instanciating the classes)

[caioaamaral]

you could initialize Qwidget parent inside SetupAssistantWidget by creating some initialize function that receives a Qwidget* as param. You could even override this function from your plugin implementation:

AuthorPlugin::initialize(QWidget* parent) override;

And then calling it just after default constructor of your plugin:

global Qwidget* parent;

AuthorPlugiin some_plugin;

some_plugiin.initialize(parent);

Given that this is a very old question, I'm going to close this out. Please feel free to reopen if you think there is something to change here.
