bpatcher

Embed a subpatch with a visible UI

Description

The bpatcher object holds the contents of a patcher or subpatcher, displaying only those visual elements that fall within its box rectangle. The number of inlets and outlets in a bpatcher object is determined by the number of inlet and outlet objects contained in its contained subpatcher.

Discussion

The inlet to the bpatcher object is used for sending messages to its contained patcher, not for sending messages to or setting attributes on the bpatcher object itself. Setting an attribute or sending a message to the bpatcher object must be done via scripting messages to the thispatcher object. See the replace message for an example.

Arguments

None.

Attributes

args[256 atoms]:

The args attribute lets you set arguments passed to your patcher that will be saved with the bpatcher in its parent patcher. Arguments can replace #1 - #9 in the contained patcher and/or parsed by the patcherargs object.

bgcolor[4 floats]: 1. 1. 1. 1.

Sets the background color of the patcher visible in the bpatcher window.

bgmode[int]: 0

Determines how the bpatcher draws its background Possible values:

0 = 'Transparent' ( Don't draw the background )
1 = 'Patcher Background Color' ( Draw background using the contained patcher's bgcolor )
2 = 'Override Background Color' ( Use the bpatcher object's bgcolor to draw the background )

border[int]: 0

When enabled, the border attribute draws a one pixel black border around the object's box

clickthrough[int]: 0

When enabled, clicks on empty space in a bpatcher are sent to any objects underneath the bpatcher in the parent patcher. Turning on clickthrough only makes sense if the bpatcher object's background is transparent.

embed[int]: 0

When enabled, embed will save the contained patcher in its parent patcher. When disabled (the default), the contained patcher is loaded from a file specified by the name attribute.

enablehscroll[int]: 0

Enables a horizontal scrollbar for scrolling the contents of the contained patcher

enablevscroll[int]: 0

Enables a vertical scrollbar for scrolling the contents of the contained patcher

lockeddragscroll[int]: 0

Determines whether you can scroll the contents of the bpatcher by holding down the shift and command (control on Windows) keys and dragging Possible values:

0 = 'Unlocked Only' ( Drag scrolling only works when the parent patcher is unlocked )
1 = 'Locked and Unlocked' ( Drag scrolling is always enabled )
2 = 'Never' ( Drag scrolling is never enabled )

lockedsize[int]: 0

When lockedsize is enabled, you cannot resize the bpatcher object's rectangle by dragging its selection rectangle. You can change the size using the inspector however.

name[symbol]: <none>

Designates the pathname of the patcher file for the bpatcher to use. The name attribute can only be set using the inspector.

offset[2 floats]: 0. 0.

Offset

Common Box Attributes

Below is a list of attributes shared by all objects. If you want to change one of these attributes for an object based on the object box, you need to place the word sendbox in front of the attribute name, or use the object's Inspector.

annotation[symbol]

Sets the text that will be displayed in the Clue window when the user moves the mouse over the object.

background[int]: 0

Adds or removes the object from the patcher's background layer. background 1 adds the object to the background layer, background 0 removes it. Objects in the background layer are shown behind all objects in the default foreground layer.

Sets the position and size of the object in the patcher window.

presentation[int]: 0

Sets whether an object belongs to the patcher's presentation.

presentation_rect[4 floats]: 0. 0. 0. 0.

Sets the x and y position and width and height of the object in the patcher's presentation, leaving its patching position unchanged.

rect[4 floats]

size[2 floats]

Sets the object's width and height in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its position unchanged.

Messages

(drag)

When a patcher file is dragged from the Max File Browser to a bpatcher object, the file will be loaded.

(mouse)

When the window containing the bpatcher object is locked (or the Command key on Macintosh or Control key on Windows is held down) and the mouse is clicked inside the bpatcher object’s box, the gesture is handled by the patch inside the box.
If the Shift and Command keys on Macintosh or Shift and Control keys on Windows are held down while clicking on a bpatcher object, dragging the mouse moves the upper-left corner of the visible part of the patch inside the box. The Assistance area of the patcher window shows the pixel values of the offset. If Enable Drag-Scrolling is unchecked in the bpatcher Inspector window, this feature is disabled.
If the Command and Option keys on Macintosh or Control and Alt keys on Windows are held down while clicking in a bpatcher object, a pop-up menu allows you to open the original file of the patch contained inside the box in its own window, or change the patch currently contained inside the box in its own window.

replace

The replace message is intended for use in conjunction with scripting messages to the thispatcher object. If you send a replace message via an inlet to the bpatcher object, it will only work if there is no patcher inside the bpatcher; the inlet to the bpatcher object is used for sending messages into its subpatcher, not for sending messages to the bpatcher object itself.
To use the replace message feature via scripting messages, give your bpatcher object a Scripting Name using the Inspector, then use the message script sendbox <bpatcher-name> replace <patcher-name> to send the message to the named bpatcher object.

Arguments:
  • filename [symbol]

Output

(User-Defined)

If the patcher being used in a bpatcher contains outlet objects, they will appear in corresponding left-to-right order as outlets in the bpatcher object's box.
