Usage
vtkRectangularButtonSource creates a rectangular shaped
button with texture coordinates suitable for application of
a texture map. This provides a way to make nice looking 3D
buttons. The buttons are represented as vtkPolyData that
includes texture coordinates and normals. The button lies in
the x-y plane.
To use this class you must define its width, height and
length. These measurements are all taken with respect to the
shoulder of the button. The shoulder is defined as follows.
Imagine a box sitting on the floor. The distance from the
floor to the top of the box is the depth; the other
directions are the length (x-direction) and height (y-
direction). In this particular widget the box can have a
smaller bottom than top. The ratio in size between bottom
and top is called the box ratio (by default=1.0). The ratio
of the texture region to the shoulder region is the texture
ratio. And finally the texture region may be out of plane
compared to the shoulder. The texture height ratio controls
this.
To create an instance of class vtkRectangularButtonSource,
simply invoke its constructor as follows
obj = vtkRectangularButtonSource
Methods
The class vtkRectangularButtonSource has several methods
that can be used. They are listed below. Note that the
documentation is translated automatically from the VTK
sources, and may not be completely intelligible. When in
doubt, consult the VTK website. In the methods listed below,
obj is an instance of the vtkRectangularButtonSource class.
* string = obj.GetClassName ()
* int = obj.IsA (string name)
* vtkRectangularButtonSource = obj.NewInstance ()
* vtkRectangularButtonSource = obj.SafeDownCast (vtkObject
o)
* obj.SetWidth (double ) - Set/Get the width of the button.
* double = obj.GetWidthMinValue () - Set/Get the width of
the button.
* double = obj.GetWidthMaxValue () - Set/Get the width of
the button.
* double = obj.GetWidth () - Set/Get the width of the
button.
* obj.SetHeight (double ) - Set/Get the height of the
button.
* double = obj.GetHeightMinValue () - Set/Get the height of
the button.
* double = obj.GetHeightMaxValue () - Set/Get the height of
the button.
* double = obj.GetHeight () - Set/Get the height of the
button.
* obj.SetDepth (double ) - Set/Get the depth of the button
(the z-eliipsoid axis length).
* double = obj.GetDepthMinValue () - Set/Get the depth of
the button (the z-eliipsoid axis length).
* double = obj.GetDepthMaxValue () - Set/Get the depth of
the button (the z-eliipsoid axis length).
* double = obj.GetDepth () - Set/Get the depth of the button
(the z-eliipsoid axis length).
* obj.SetBoxRatio (double ) - Set/Get the ratio of the
bottom of the button with the shoulder region. Numbers
greater than one produce buttons with a wider bottom than
shoulder; ratios less than one produce buttons that have a
wider shoulder than bottom.
* double = obj.GetBoxRatioMinValue () - Set/Get the ratio of
the bottom of the button with the shoulder region. Numbers
greater than one produce buttons with a wider bottom than
shoulder; ratios less than one produce buttons that have a
wider shoulder than bottom.
* double = obj.GetBoxRatioMaxValue () - Set/Get the ratio of
the bottom of the button with the shoulder region. Numbers
greater than one produce buttons with a wider bottom than
shoulder; ratios less than one produce buttons that have a
wider shoulder than bottom.
* double = obj.GetBoxRatio () - Set/Get the ratio of the
bottom of the button with the shoulder region. Numbers
greater than one produce buttons with a wider bottom than
shoulder; ratios less than one produce buttons that have a
wider shoulder than bottom.
* obj.SetTextureRatio (double ) - Set/Get the ratio of the
texture region to the shoulder region. This number must be
0<=tr<=1. If the texture style is to fit the image, then
satisfying the texture ratio may only be possible in one
of the two directions (length or width) depending on the
dimensions of the texture.
* double = obj.GetTextureRatioMinValue () - Set/Get the
ratio of the texture region to the shoulder region. This
number must be 0<=tr<=1. If the texture style is to fit
the image, then satisfying the texture ratio may only be
possible in one of the two directions (length or width)
depending on the dimensions of the texture.
* double = obj.GetTextureRatioMaxValue () - Set/Get the
ratio of the texture region to the shoulder region. This
number must be 0<=tr<=1. If the texture style is to fit
the image, then satisfying the texture ratio may only be
possible in one of the two directions (length or width)
depending on the dimensions of the texture.
* double = obj.GetTextureRatio () - Set/Get the ratio of the
texture region to the shoulder region. This number must be
0<=tr<=1. If the texture style is to fit the image, then
satisfying the texture ratio may only be possible in one
of the two directions (length or width) depending on the
dimensions of the texture.
* obj.SetTextureHeightRatio (double ) - Set/Get the ratio of
the height of the texture region to the shoulder height.
Values greater than 1.0 yield convex buttons with the
texture region raised above the shoulder. Values less than
1.0 yield concave buttons with the texture region below
the shoulder.
* double = obj.GetTextureHeightRatioMinValue () - Set/Get
the ratio of the height of the texture region to the
shoulder height. Values greater than 1.0 yield convex
buttons with the texture region raised above the shoulder.
Values less than 1.0 yield concave buttons with the
texture region below the shoulder.
* double = obj.GetTextureHeightRatioMaxValue () - Set/Get
the ratio of the height of the texture region to the
shoulder height. Values greater than 1.0 yield convex
buttons with the texture region raised above the shoulder.
Values less than 1.0 yield concave buttons with the
texture region below the shoulder.
* double = obj.GetTextureHeightRatio () - Set/Get the ratio
of the height of the texture region to the shoulder
height. Values greater than 1.0 yield convex buttons with
the texture region raised above the shoulder. Values less
than 1.0 yield concave buttons with the texture region
below the shoulder.
