This method counts the number of lines a text will occupy in respect to a given maximal width.

wWidth of cells. If 0, they extend up to the right margin of the page.
hHeight of cells.
txtString to print
halignAllows to center or align the text. Possible values are:

  • wxPDF_ALIGN_LEFT align the text at the left margin
  • wxPDF_ALIGN_CENTER center the text
  • wxPDF_ALIGN_RIGHT align the text at the right margin
  • wxPDF_ALIGN_JUSTIFY justify the text (default)
valignAllows to vertical align the text. Possible values are:

  • wxPDF_ALIGN_TOP align the text at the top of the box
  • wxPDF_ALIGN_MIDDLE center the text vertically in the box
  • wxPDF_ALIGN_BOTTOM align the text at the bottom of the box
borderIndicates if borders must be drawn around the text box. The value can be

  • wxPDF_BORDER_NONE no border
  • wxPDF_BORDER_LEFT left border
  • wxPDF_BORDER_RIGHT right border
