Gradient.property
Description
Settings that control the gradient display in a DataWindow
object. Gradient display properties are not supported in RichText,
Graph, or OLE DataWindow presentation styles.
Applies to
DataWindows
Syntax
PowerBuilder dot notation:
dw_control.Object.datawindow.gradient.property
Describe and Modify argument:
"DataWindow.gradient.property { = value }"
Parameter

Description
|
|---|
property
|
A property for the gradient. Properties
and their settings are listed in the table that follows.
|
value
|
The value to be assigned to the property.
For gradient properties, value can
be a quoted DataWindow expression.
|
Property for Gradient
|
Value
|
|---|
Angle
|
An integer indicating the angle in degrees
(values are 0 to 360) used to offset the color and transparency
gradient. This property is used only when datawindow.brushmode takes
values of 3 or 4.
Painter: Background tab, Gradient group.
|
Color
|
The gradient color of the DataWindow.
This property is only in effect when datawindow.brushmode takes
values 1 through 5.
Painter: Background tab, Gradient group
|
Focus
|
An integer in the range 0 to 100, specifying
the distance (as a percentage) from the center where the background
color is at its maximum. (For example, if the radial gradient is
used and the value is set to 0, the color will be at the center
of the background; if the value is set to 100, the color will be
at the edges of the background.)
Painter: Background tab, Gradient group
|
Repetition.Mode
|
Specifies the mode for determining the
number of gradient transitions.
Permitted values and their meanings are:
Painter: Background tab, Gradient group.
|
Repetition.Count
|
An integer specifying the number of gradient
transitions for background color and transparency. A value of 0
indicates 1 transition. A value of 3 indicates 4 transitions. This
property is used only when the datawindow.brushmode property takes
values from 1 to 4 and when the when the datawindow.gradient.repetition.mode
value is 0 (by count). The maximum is 10,000.
Painter: Background tab, Gradient group.
|
Repetition.Length
|
A long specifying the number of gradient
transitions. This property is used only when the datawindow.brushmode
property takes values from 1 to 4 and the datawindow.gradient.repetition.mode
property takes the value of 1 (by length). The units for the length
that you assign for gradient transitions are set by the datawindow.units
property.
Painter: Background tab, Gradient group.
|
Scale
|
An integer in the range 0 to 100 specifying
the rate of transition to the gradient color (as a percentage).
Painter: Background tab, Gradient group
|
Spread
|
An integer in the range 0 to 100 indicating
the contribution of the second color to the blend (as a percentage).
Painter: Background tab, Gradient group
|
Tranparency
|
An integer in the range 0 to 100, where
0 means that the secondary (gradient) background is opaque and 100
that it is completely transparent. The gradient defines transitions
between the primary and secondary transparency settings.
Painter: Background tab, Gradient group
|
Usage
In the painter
Select the DataWindow object and set the value on the Background
tab of the Properties view.
If you save to an EMF or WMF, the properties on the Background
tab are not saved with the DataWindow.
Examples
Example 1
string ls_data
ls_data = dw_1.Object.datawindow.brushmode
dw_1.Object.datawindow.Brushmode = 5
ls_data = dw_1.Describe("datawindow.brushmode")
dw_1.Modify("datawindow.Brushmode=6")
dw_1.Modify("datawindow.Gradient.Transparency=75")
