QtUtils

A collection of utilities for (not only) Qt development. At this moment it contains only a few header-only classes which can be used anywhere in your code. The code is intended to be simple, light-weight, pragmatic and easy to understand. More stuff will be added later on...

Layouts

File: layouts.h

I hate creating complicated layouts in QtDesigner as much as you do. If you tried it at least once, you know what I am talking about. But I also hate writing and reading complex and verbose procedural code. So I created a few utility classes in layouts.h which will allow writing more concise layout-related code in somewhat declarative style. Currently it only contains helpers for QVBoxLayout and QHBoxLayout, which however account for more than 90 % of all layouts in my code.

There are two templated wrappers VBox and HBox around pointers to QVBoxLayout and QHBoxLayout. These wrappers allow implicit conversions to the undelying layout pointers, they provide << operators with which you can add child widgets or child layouts in a declarative way. You can also add stretches (using Stretch) or spacings (using Spacing). You can also easily define margins and default spacing for the layout in wrapper constructors. And if you need more, you can always access the layout pointer with -> operator.

An example with easy-to-read layout hierarchy, coded in a declarative-like style:

auto dialog = new QDialog();
auto icon = new QLabel();
auto text = new QLabel("A message ...");
auto ok = new QPushButton("Ok");
auto cancel = new QPushButton("Cancel");

HBox(dialog)
    << (VBox() 
        << icon
        << Stretch())
    << Spacing(16)
    << (VBox() 
        << text 
        << Stretch() 
        << (HBox()
            << Stretch()
            << ok
            << cancel));

More examples are in layouts.h.
