8 drscheme:get/extend

(drscheme:get/extend:extend-tab mixin) → void?
  mixin : (make-mixin-contract drscheme:unit:tab<%>)
(drscheme:get/extend:extend-tab mixin    
  before?) → void?
  mixin : (make-mixin-contract drscheme:unit:tab<%>)
  before? : boolean?
This class implements the tabs in drscheme. One is created for each tab in a frame (each frame always has at least one tab, even if the tab bar is not shown)

The argument, before, controls if the mixin is applied before or after already installed mixins. If unsupplied, this is the same as supplying #t.
(drscheme:get/extend:extend-interactions-text mixin) → void?
  mixin : (make-mixin-contract drscheme:rep:text<%>)
(drscheme:get/extend:extend-interactions-text mixin    
  before?) → void?
  mixin : (make-mixin-contract drscheme:rep:text<%>)
  before? : boolean?
This text is used in the bottom window of drscheme frames.

The argument, before, controls if the mixin is applied before or after already installed mixins. If unsupplied, this is the same as supplying #t.
(drscheme:get/extend:get-interactions-text)
 → (implementation?/c drscheme:rep:text<%>)
Once this function is called, drscheme:get/extend:extend-interactions-text raises an error, disallowing any more extensions.
(drscheme:get/extend:extend-definitions-text mixin) → void?
  mixin : (make-mixin-contract drscheme:unit:definitions-text<%>)
(drscheme:get/extend:extend-definitions-text mixin    
  before?) → void?
  mixin : (make-mixin-contract drscheme:unit:definitions-text<%>)
  before? : boolean?
This text is used in the top window of drscheme frames.

The argument, before, controls if the mixin is applied before or after already installed mixins. If unsupplied, this is the same as supplying #f.
(drscheme:get/extend:get-definitions-text)
 → (implementation?/c drscheme:unit:definitions-text<%>)
Once this function is called, drscheme:get/extend:extend-definitions-text raises an error, disallowing any more extensions.
(drscheme:get/extend:extend-interactions-canvas mixin) → void?
  mixin : (make-mixin-contract drscheme:unit:interactions-canvas%)
(drscheme:get/extend:extend-interactions-canvas mixin 
  before?) 
 → void?
  mixin : (make-mixin-contract drscheme:unit:interactions-canvas%)
  before? : boolean?
This canvas is used in the bottom window of drscheme frames.

The argument, before, controls if the mixin is applied before or after already installed mixins. If unsupplied, this is the same as supplying #f.
(drscheme:get/extend:get-interactions-canvas)
 → (subclass?/c drscheme:unit:interactions-canvas%)
Once this function is called, drscheme:get/extend:extend-interactions-canvas raises an error, disallowing any more extensions.
(drscheme:get/extend:extend-definitions-canvas mixin) → void?
  mixin : (make-mixin-contract drscheme:unit:definitions-canvas%)
(drscheme:get/extend:extend-definitions-canvas mixin    
  before?) → void?
  mixin : (make-mixin-contract drscheme:unit:definitions-canvas%)
  before? : boolean?
This canvas is used in the top window of drscheme frames.

The argument, before, controls if the mixin is applied before or after already installed mixins. If unsupplied, this is the same as supplying #f.
(drscheme:get/extend:get-definitions-canvas)
 → (subclass?/c drscheme:unit:definitions-canvas%)
Once this function is called, drscheme:get/extend:extend-definitions-canvas raises an error, disallowing any more extensions.
(drscheme:get/extend:extend-unit-frame mixin) → void?
  mixin : (make-mixin-contract drscheme:unit:frame%)
(drscheme:get/extend:extend-unit-frame mixin    
  before?) → void?
  mixin : (make-mixin-contract drscheme:unit:frame%)
  before? : boolean?
This is the frame that implements the main drscheme window.

The argument, before, controls if the mixin is applied before or after already installed mixins. If unsupplied, this is the same as supplying #f.
(drscheme:get/extend:get-unit-frame)
 → (subclass?/c drscheme:unit:frame%)
Once this function is called, drscheme:get/extend:extend-unit-frame raises an error, disallowing any more extensions.
