2021-08-18Userland+LibGUI: Add shorthand versions of the Margins constructorsin-ack
This allows for typing [8] instead of [8, 8, 8, 8] to specify the same margin on all edges, for example. The constructors follow CSS' style of specifying margins. The added constructors are: - Margins(int all): Sets the same margin on all edges. - Margins(int vertical, int horizontal): Sets the first argument to top and bottom margins, and the second argument to left and right margins. - Margins(int top, int vertical, int bottom): Sets the first argument to the top margin, the second argument to the left and right margins, and the third argument to the bottom margin.
2021-08-18Userland+LibGUI: Make Margins arguments match CSS orderingsin-ack
Previously the argument order for Margins was (left, top, right, bottom). To make it more familiar and closer to how CSS does it, the argument order is now (top, right, bottom, left).
2021-06-06AK+Everywhere: Disallow constructing Functions from incompatible typesAli Mohammad Pur
Previously, AK::Function would accept _any_ callable type, and try to call it when called, first with the given set of arguments, then with zero arguments, and if all of those failed, it would simply not call the function and **return a value-constructed Out type**. This lead to many, many, many hard to debug situations when someone forgot a `const` in their lambda argument types, and many cases of people taking zero arguments in their lambdas to ignore them. This commit reworks the Function interface to not include any such surprising behaviour, if your function instance is not callable with the declared argument set of the Function, it can simply not be assigned to that Function instance, end of story.

Instead use default_font().bold_variant() in cases where we want a bold variant of the default font. :^)

2021-03-22LibGUI: Allow a wizard page to return null as its next pageAnotherTest
2021-02-27LibGUI: add a rudimentary framework for Wizards.Nick Vella
This patch provides the basic components needed for developers to create consistent wizard interface experiences in their applications. `WizardDialog` provides the dialog frame for the wizard, handling navigation and presentation. `AbstractWizardPage`s form the base class of Wizard pages, which are pushed onto the `WizardDialog` page stack via `WizardDialog::push_page`. `CoverWizardPage` and `WizardPage` are provided to ease the creation of Wizard interfaces consistent with the Serenity visual language.
