member this.GetPoint : System.Windows.Forms.VisualStyles.PointProperty -> System.Drawing.Point
Public Function GetPoint (prop As PointProperty) As Point
Parameters
- prop
- PointProperty
One of the PointProperty values that specifies which property value to retrieve for the current visual style element.

parameter for the current visual style element.
Exceptions

is not one of the PointProperty values.
Examples
The following code example demonstrates how to use the GetPoint method in a custom control to get the offset of the window Close button in relation to the upper-right corner of the title bar. This code example is part of a larger example provided for the VisualStyleRenderer class overview.
// Get the sizes and offsets for the window parts as specified
// by the visual style.
private:
void GetPartDetails()
{
// Do nothing further if visual styles are not enabled.
if (!Application::RenderWithVisualStyles)
{
return;
}
Graphics^ g = this->CreateGraphics();
// Get the size and offset of the close button.
if (SetRenderer(windowElements["windowClose"]))
{
closeButtonSize =
renderer->GetPartSize(g, ThemeSizeType::True);
closeButtonOffset =
renderer->GetPoint(PointProperty::Offset);
}
// Get the height of the window caption.
if (SetRenderer(windowElements["windowCaption"]))
{
captionHeight = renderer->GetPartSize(g,
ThemeSizeType::True).Height;
}
// Get the thickness of the left, bottom,
// and right window frame.
if (SetRenderer(windowElements["windowLeft"]))
{
frameThickness = renderer->GetPartSize(g,
ThemeSizeType::True).Width;
}
// Get the size of the resizing gripper.
if (SetRenderer(windowElements["statusGripper"]))
{
gripperSize = renderer->GetPartSize(g,
ThemeSizeType::True);
}
}
// Get the sizes and offsets for the window parts as specified
// by the visual style.
private void GetPartDetails()
{
// Do nothing further if visual styles are not enabled.
if (!Application.RenderWithVisualStyles)
{
return;
}
using (Graphics g = this.CreateGraphics())
{
// Get the size and offset of the close button.
if (SetRenderer(windowElements["windowClose"]))
{
closeButtonSize =
renderer.GetPartSize(g, ThemeSizeType.True);
closeButtonOffset =
renderer.GetPoint(PointProperty.Offset);
}
// Get the height of the window caption.
if (SetRenderer(windowElements["windowCaption"]))
{
captionHeight = renderer.GetPartSize(g,
ThemeSizeType.True).Height;
}
// Get the thickness of the left, bottom,
// and right window frame.
if (SetRenderer(windowElements["windowLeft"]))
{
frameThickness = renderer.GetPartSize(g,
ThemeSizeType.True).Width;
}
// Get the size of the resizing gripper.
if (SetRenderer(windowElements["statusGripper"]))
{
gripperSize = renderer.GetPartSize(g,
ThemeSizeType.True);
}
}
}

End Using

Remarks
Visual styles use a set of point values to describe some properties of the elements defined by a style. These properties are encapsulated by the PointProperty values.
