Hi Viktor, you are right, I'd personally prefer use native libs too, but in this case, I need use plugins for compatibility with dinamic Qt and with other funcionalities
ex: To use images and displaying these, I use the followed code: oPixmap := QPixmap():new() oPixmap:load( ":myimage" ) // load an image from resources oImage := QLabel():new() oImage:setPixmap( oPixmap:pPtr ) // associate Pixmap for show it oImage:move( x , y ) oImage:size( w , h ) oImage:show() In Dinamic Mode: This simplified code work fine with BMP, PNG and JPG In Static Mode: This simplified code work fine with BMP and PNG (don't work with JPG because it need the plugin) If I load JPG plugin, this is transparent for me and my program work fine with JPG too. If I use native Harbour Lib to load JPG image, I can not use the QPixmap class. The jpg plugin is use to illustrate an plugin implementation, but other plugins will be necesaries in the future too. Remember that my english is very poor !!! sorry.
