jit.gl.picker
Description
The jit.gl.picker object responds to mouse interaction in the destination by reporting the name of jit.gl (OB3D) objects intersecting with the mouse.
Examples
Discussion
This object requires one argument: the name of a drawing context. A named drawing context is a named instance of a jit.window, jit.pwindow, or jit.matrix object that has an instance of the jit.gl.render object associated with it. Additionally it can reference the name of a jit.gl.node sub-context. This value may also be set via the OB3D drawto attribute. If no argument is present, the object is implicitly added to the first valid drawing context or sub-context found in the current patch or by searching up the patcher hierarchy.
Attributes
filters [10 symbols]
Specify a list of filterclass names that can be picked (default = all). Possible values include all and default . Additional values include any user-specified filterclass names (maximum allowed = 10).
hover [int]
Enable mouse hovering (default = 1)
ui_priority [int]
UI priority value (default = -1000). When multiple UI objects are listening to the same window, ui_priority determines the order objects receive input. Lower values test first.
Common Box Attributes
annotation [symbol]
Sets the text that will be displayed in the Clue window when the user moves the mouse over the object.
background [int] (default: 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.
color [4 floats]
Sets the color for the object box outline.
fontface [int]
Sets the type style used by the object. The options are:
plain
bold
italic
bold italic
Possible values:
0 = 'regular'
1 = 'bold'
2 = 'italic'
3 = 'bold italic'
fontname [symbol]
Sets the object's font.
fontsize [float]
Sets the object's font size (in points).
Possible values:
'8'
'9'
'10'
'11'
'12'
'13'
'14'
'16'
'18'
'20'
'24'
'30'
'36'
'48'
'64'
'72'
hidden [int] (default: 0)
Toggles whether an object is hidden when the patcher is locked.
hint [symbol]
Sets the text that will be displayed in as a pop-up hint when the user moves the mouse over the object in a locked patcher.
ignoreclick [int] (default: 0)
Toggles whether an object ignores mouse clicks in a locked patcher.
jspainterfile [symbol]
JS Painter File
patching_rect [4 floats] (default: 0. 0. 100. 0.)
Sets the position and size of the object in the patcher window.
position [2 floats]
Sets the object's x and y position in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its size unchanged.
presentation [int] (default: 0)
Sets whether an object belongs to the patcher's presentation.
presentation_rect [4 floats] (default: 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]
Sets the x and y position and width and height of the object in both patching and presentation modes (if the object belongs to its patcher's presentation).
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.
textcolor [4 floats]
Sets the color for the object's text in RGBA format.
textjustification [int]
Sets the justification for the object's text.
Possible values:
0 = 'left'
1 = 'center'
2 = 'right'
varname [symbol]
Sets the patcher's scripting name, which can be used to address the object by name in pattr, scripting messages to thispatcher, and the js object.
OB3D Attributes
anim [symbol]
The name of a jit.anim.node object that handles all spatial transforms for this instance (default = UID). The default value references an internal object, but can be overridden by setting to the name of an existing external jit.anim.node instance. This allows for more advanced control of the spatial transform.
anchor [3 floats]
The anchor position in local space (default = 0. 0. 0.). Allows for offsetting the local 3D origin around which transforms are applied.
animmode [symbol]
Determines which space the anim_move and anim_turn messages will affect the position and orientation of this object (default = parent).
local = Rotate relative to local axis
parent = Rotate relative to parent axis
world = Rotate relative to world axis
axes [int]
x/y/z axis rendering off/on (default = 0)
drawto [symbol]
The named drawing context in which to draw (default = none) A named drawing context is a named instance of a jit.window, jit.pwindow, or jit.matrix object that has an instance of the jit.gl.render object associated with it.
enable [int]
Enable flag (default = 1) When the flag is set, drawing is enabled.
layer [int]
Object layer number (default = 0) When in automatic mode, the layer number determines the rendering order (low to high). Objects in the same layer have no guarantee which will be rendered first.
name [symbol]
The instance name (default = UID)
position [3 floats]
The 3D origin in the form x y z (default = 0. 0. 0.)
