Windows
Simple, flexable window controls in Unity
Introduction
1
public static class API.Windows
Copied!
Manage RectTransfroms as if they where windows similar to the functionality you would find developing form based applications for Windows and similar operating systems.
What can it do?
You can add a Window component to any RecTransform to enable the Windows interface to manage that rect as if it where a window. Companion componenets can be used to enable drag to move and resizing funcitonality while the interface its self and features on the Window component can be used to perfrom common window tasks such as minimize, maximize, restore, docking operations, snap to edge and more.
Events
Window Focus Changed
1
API.Windows.EventWindowFocusedChanged
Copied!
Invoked when the currently focused window changes. This event will indicate the previously focused and newly focused windows. Note that it is possible that no window was or is now focused thus either can be null.
Concepts
Window
Though commonly used with uGUI it is not strictly limited to UnityEngine.UI aka uGUI. The Windows API works with RectTransform and the Camera componenets in Unity to manage this rect, what is placed within and how it is rendered is not relivent to the windows interface so you can use anything available in Unity without an issue.
The Window componenet contains much of the same funcitonality you will find in the static API and is defined on a GameObject. It may be simpler in many cases to use the Componenet as opposed to using the API directly.
Focus
A focused window is the window which is currently handling input. This is simulated in Unity by identifying the window where the user last interacted with a UI element or where you have last called "Focus" on the Windows api.
The focused window is automatically moved to the top ... that is, its location in the game object structure will be moved to be the top most child in its current parent and thus Unity will render it on top of all other siblings.
Clamping
A typical requirement is that a window not be aloud to move or resize outside the bounds of its parent's rect. As such the WIndows API and related components can optionally enforce this restriciton insuring the window cannot be moved or resized through the use of the API to exceed the bounds of the parent rect.
Tags
This system makes use of the System Core Tags concept which can be used to search for a given window.
How To
Set a window as focused
In most cases you do not need to set this your self. The Window componenet will set windows as focused when the user interacts with them through normal UI controls. In some cases however it can be useful to set a window as focused from code such as to force it to come to the top of the view.
1
API.Windows.Focused = window;

Get the focused window
You can read the focused window at any time.
1
var window = API.Windows.Focused;

Set size and position
There are a number of ways to set the size and position of a window.
The Window componenet has similar methods to ones shown here in addition the Move Handle and Border Handle componenets can modify position and size through mouse inputs.
1
API.Windows.SetTransform(window, transform);
Copied!
This overload will cause the window to match the RectTransform position and size. Note this does not make the window a child of the indicated transform it simply matches its positon and size. This is most offten used to quickly dock a window to particular place and size.
1
API.Windows.SetTransform(window, postion, size);
Copied!
As the paramiters sugest this will set the size and position of the window in question. Note that position is local space and the pivot point and anchor point considered is always (0.5,0.5) e.g. the middle of the window and middle of the parent.
Min, Max and Restore
Windows can be minimized, maximized and restored to there previous size and position on demand. This works much the same as the minimize, maximize and restore features of the Windows operating system's windows.
Maximize means to match the size and position of the parent and is the same as calling SetTransform(window, window's parent);
Minimize means to reduce the windows size to its configured minimal size. If if you wanted to hide the window and show an icon instead you would simply disable the window game object and enable an icon to act as its proxy.
Calculate Clamp
Clamping means to restrict the window to the bounds of its parent, that is limit the windows size and position such that it falls wholly within its parent's rect. You can test for a windows "clamping bounds" by calling
1
var bounds = API.Windows.PositionBounds(window);
Copied!
You can also calculate the valid clamped position of any given position via
1
var validPos = API.Windows.ClampPosition(window, position);
Copied!
Finding Windows
Only registered windows can be found and listed. The Window componenet will automatically register and deregister windows on creation and destroy of the window.
You can get a list of all registered windows at any time.
1
var availableWindows = API.Windows.GetAvailableWindows();
Copied!
you can also search for a window based on its scriptable tag or even a Unity tag.
It is not recomended to use Unity's tag system.
Find the first matching 1 tag
1
var window = API.Windows.FindWindowWithTag(tag);
Copied!
or find all matching 1 tag
1
var windows = API.Windows.FindWindowsWithTag(tag);
Copied!
or fiind the first matching multiple tags
1
var window = API.Windows.FindWindowWithTags(tags);
Copied!
or find all matching multiple tags
1
var windows = API.Windows.FindWindowsWitthTags(tags);
Copied!
or find the first window matching a Unity tag
1
var window = API.Windows.FindWindowWithUnityTag("Dont Do This");
Copied!
or find all windows matching a Unity tag
1
var window = API.Windows.FindWindowsWithUnityTag("Dont Do This");
Copied!
