HVIEWER

HVIEWER N

CREATES A SYSTEM OBJECT HVIEWER AND ALLOCATES IT NUMBER N AS REFERENCE

  • Type: Command
  • Parameter: 1
  • Group: System Objects Creation

ACTION

The command HVIEWER N creates a system object HVIEWER, and allocates it a number N. The number N will be used to designate the HVIEWER.

The created HVIEWER can then be used through the appropriated commands.

The HVIEWER is created at position (0,0) : that is TOP = 0 pixel and LEFT = 0 pixel, with dimensions: WIDTH = 185 pixels and HEIGHT = 105 pixels.

A HVIEWER displays a HTML formated file with command FILE_LOAD.

A HVIEWER generates the event ON_CLICK.

Remark: by default, the HVIEWER is created on the FORM number 0, but another FORM can be used. For that, create a FORM by FORM N, and send it all the commands by COMMAND_TARGET_IS N before creating the HVIEWER.

SYNTAX: HVIEWER N

  • N = system object number (integer or real). Must be greater than 0 and less than or equal to the allowed maximum number of system objects.

USE

  • A HVIEWER is used to display a HTML formated file (with command FILE_LOAD).

ERROR

  • If number N is not a correct expression.
  • If number N exceeds the allowed maximum number of system objects.
  • If number N is less than or equal to 0.
  • If number N is already used for a system object number.
