Detailed Description

represent a seven segment display class

Member Function Documentation

§ measure_control()

drawing::size xtd::forms::seven_segment_display::measure_control ( ) const
inlineoverrideprotectedvirtual

Measure this control.

Returns
The drawing::size size of this control.
Remarks
This metod is not relevant for this class.

Reimplemented from xtd::forms::control.

§ set_bounds_core()

void xtd::forms::seven_segment_display::set_bounds_core ( int32_t  x,
int32_t  y,
int32_t  width,
int32_t  height,
bounds_specified  specified 
)
inlineoverrideprotectedvirtual

Performs the work of setting the specified bounds of this control.

Parameters
xThe new left property value of the control.
yThe new top property value of the control.
widthThe new width property value of the control.
heightThe new height property value of the control.
specifiedA bitwise combination of the bounds_specified values.
Remarks
Typically, the parameters that correspond to the bounds not included in the specified parameter are passed in with their current values. For example, the height, width, or the y or y properties of the location property can be passed in with a reference to the current instance of the control. However all values passed in are honored and applied to the control.
The specified parameter represents the elements of the controls Bounds changed by your application. For example, if you change the size of the control, the specified parameter value is the size value of bounds_specified. However, if the size is adjusted in response to the dock property being set, the pecified parameter value is the none value of bounds_specified.
Notes to Inheritors
When overriding set_bounds_core(int32_t, int32_t, int32_t, int32_t, bounds_specified) in a derived class, be sure to call the base class's set_bounds_core(int32_t, int32_t, int32_t, int32_t, bounds_specified) method to force the bounds of the control to change. Derived classes can add size restrictions to the set_bounds_core(int32_t, int32_t, int32_t, int32_t, bounds_specified) method.

Reimplemented from xtd::forms::control.

§ set_client_size_core()

void xtd::forms::seven_segment_display::set_client_size_core ( int32_t  width,
int32_t  height 
)
inlineoverrideprotectedvirtual

Sets the size of the client area of the control.

Parameters
widthThe client area width, in pixels.
heightThe client area height, in pixels.
Remarks
The client area starts at the (0, 0) location and extends to the (width, height) location.
Typically, you should not set the client_size of the control.
Notes to Inheritors
When overriding set_client_size_core(int32_t, int32_t) in a derived class, be sure to call the base class's set_client_size_core(int32_t, int32_t) method so that the client_size property is adjusted.

Reimplemented from xtd::forms::control.
