Hi, I am a quite newbie to VTK.
I am involving in a project. I consider to write a VTK mouse picking method
in C++ code. I know the sample Tcl code, partially as following:

# Create a text mapper and actor to display the results of picking.
vtkTextMapper textMapper
set tprop [textMapper GetTextProperty]
    $tprop SetFontFamilyToArial
    $tprop SetFontSize 10
    $tprop BoldOn
    $tprop ShadowOn
    $tprop SetColor 1 0 0
vtkActor2D textActor
    textActor VisibilityOff
    textActor SetMapper textMapper

in the sample, tprop is created, but what kind of object it is?
vtkTextProperty or vtkProperty? Or i dunt need to specify the type of
object?
Can anybody help me what is the code in C++ ???

vtkTextMapper textMapper
set tprop [textMapper GetTextProperty]

set selPt [picker GetSelectionPoint]
set x [lindex $selPt 0]
set y [lindex $selPt 1]
set pickPos [picker GetPickPosition]
set xp [lindex $pickPos 0]
set yp [lindex $pickPos 1]
set zp [lindex $pickPos 2]


Thanks very much!
