Instance Method Detail

def begin(items_count : Int32, items_height : Float32 = -1.0) : Void #

ImGuiListClipper::Begin()


[View source]
def display_end : Int32 #

[View source]
def display_end=(display_end : Int32) #

[View source]
def display_start : Int32 #

[View source]
def display_start=(display_start : Int32) #

[View source]
def end : Void #

Automatically called on the last call of Step() that returns false.

ImGuiListClipper::End()


[View source]
def force_display_range_by_indices(item_min : Int32, item_max : Int32) : Void #

item_max is exclusive e.g. use (42, 42+1) to make item 42 always visible BUT due to alignment/padding of certain items it is likely that an extra item may be included on either end of the display range.

ImGuiListClipper::ForceDisplayRangeByIndices()


[View source]
def items_count : Int32 #

[View source]
def items_count=(items_count : Int32) #

[View source]
def items_height : Float32 #

[View source]
def items_height=(items_height : Float32) #

[View source]
def start_pos_y : Float32 #

[View source]
def start_pos_y=(start_pos_y : Float32) #

[View source]
def step : Bool #

Call until it returns false. The DisplayStart/DisplayEnd fields will be set and you can process/draw those items.
