SCWindow Cocoa user interface window

Inherits from: Object

A class representing a user interface window in the Cocoa gui system on OSX.

Besides providing a window in which to host SCView, SCWindow is also a canvas on which you can draw using Pen. See the SCPen file for many examples.

For modal versions of SCWindow see SCModalWindow and SCModalSheet.

Some Important Issues Regarding SCWindow

If you try to set parameters of a Window or a GUI widget from a Routine , which uses the SystemClock by default, you must wrap it in a deferred function: { myWindow.bounds_( Rect(100,500,200,200) ) }.defer . You do not need to use .defer, if you use the AppClock.

Creation / Class Methods

*new(name, bounds, resizable, border, server, scroll)

Creates a new SCWindow instance. You will need to call front (see below) on it before it will be visible.

name - The name that will be displayed in the title bar. An instance of String or Symbol. The default is 'panel'.

bounds - A Rect specifying the location and size of the window. The size does not include the title bar. N.B. Location is measured from the bottom left of the screen. This is different from view location, which is measured from the upper left of the window (not including the title bar). The default is Rect(128, 64, 400, 400).

resizable - A Boolean indicating whether this window can be resized by the user. The default is true.

border - A Boolean indicating whether this window has a border. Borderless windows have no title bar and thus can only be closed in code. The default is true.

server - This is a dummy argument which is here to provide compatibility with SwingOSC and has no effect. See GUI for more details.

scroll - A Boolean indicating whether this window will add scrollers if its contents exceed its bounds. If this is set to true resize settings will be ignored for enclosed views. See SCScrollTopView. The default is false.

w = Window.new;

w.front; // draw it and bring it to the front

*allWindows

Returns an Array of all open SCWindows.

*initAction

*initAction_(func)

Get/set and action to be performed when any window is created.

func - An instance of Function or FunctionList

*closeAll

Closes all open SCWindows.

*screenBounds

Returns a Rect indicating the bounds of the current screen in pixels.

Instance Methods

addFlowLayout(margin, gap)

A convenience utility which sets view.decorator to FlowLayout and returens the decorator. See FlowLayout for examples.

margin - An instance of Point

gap - An instance of Point

acceptsClickThrough_(boolean)

acceptsClickThrough

Set or return a Boolean indicating whether or not the window receives clicks when it is not front-most. The default is true.

acceptsMouseOver_(boolean)

acceptsMouseOver

Set or return a Boolean indicating whether or not the window receives mouseOver events. The default is false.

alpha_(alpha)

Set the transparency of this window. alpha is a Float between 0.0 (invisible) and 1.0 (opaque).

alwaysOnTop_(bool)

alwaysOnTop

Set or return a Boolean value indicating whether this window is always front-most. The default is false.

bounds_(argBounds)

bounds

Set or return a Rect corresponding to the location and size of the window. The size does not include the title bar. N.B. Location is measured from the bottom left of the screen. This is different from view location, which is measured from the upper left of the window (not including the title bar). Note that because of the way Cocoa applications work, setting the bounds doesn't complete until the application finishes its current application event cycle. Thus, if you check the bounds in the same chunk of code, the SCWindow will not yet return the updated values.

(

w = Window.new("test");

w.front;

w.bounds = Rect(150, 450, 150, 150);

w.bounds.postln; // still the old bounds

{ w.bounds.postln; nil }.defer(0.1); // next application event cycle

)

close

Closes this window.

drawHook_(function)

drawHook

Set or return a drawing Function. See Pen for more information and many examples.

front

Display this window and bring it to the front.

fullScreen

endFullScreen

Puts the window in or out of full screen mode. Putting a window into fullScreen mode may change its bounds.

Use the escape key to exit full screen mode and close the window.

(

w = Window.new(border: false);

w.view.background_(Color.rand);

w.front;

w.fullScreen;

Button.new(w, Rect(200,200,200,200)).states_([["Close Window"]]).action_({w.endFullScreen;w.close});

)

isClosed

Returns a Boolean indicating whether this window has been closed.

minimize

Minimize this window to the dock.

name_(argName)

name

Set or return a String corresponding to the text in this window's title bar.

onClose_(val)

onClose

Set or return a Function to be evaluated when the window is closed.

refresh

Force this window and its contents to redraw. This is sometimes necessary in order to update drawing.

setInnerExtent(width,height)

Changes the size of this window while keeping the top left corner fixed. This is the usual desired behavior, as by default Cocoa uses a flipped coordinate system.

userCanClose_(bool)

userCanClose

Set or return a Boolean value indicating whether the user can close this window by clicking on its close button. The default is true.

view

asView

Returns this window's top level view, which contains all of its other views. This will be an instance of SCTopView or SCScrollTopView depending on the value passed to the scroll argument when the window was created. See *new above.

currentSheet

Returnscurrent modal sheet attached to this window, if it exists. See SCModalSheet
