enter image description here

apparent image label on left taking space. how can fix this?

a horizontal layout give each widget equal amount of space default, can adjust ratio this:

    layout.addwidget(self.icon_button, 1)     layout.addlayout(title_layout, 3)

so gives title 3 times space icon.
