Parameters

Variable

Description

Variable

Description

ID

Control ID number. It must be an integer between 1 and 32767 and be unique within a given top-level window.

x

Horizontal position of the upper-left corner of the control in current units.

y

Vertical position of the upper-left corner of the control in current units.

width

Width of the control in current units.

height

Height of the control in current units.

html

Initial HTML value.

flags

Control flags, as follows:

Flag  Description
$0000$Click on table rows to create a custom flag string.
$0001$ Sets the control to be initially disabled.
$0002$ Sets the toolbar to be initially minimized (if supported by the client).
$0004$ Selects the basic toolbar (if supported by the client).
$0010$ Sets the control to be initially invisible.
$0800$ Draws a recessed client edge around the control.
$1000$ Draws a raised edge around the control.
chromium_switches$

In BBj 20.20 and higher, this optional string can specify an arbitrary number of space-delimited Chromium command-line switches (e.g. "--remote-debugging-port=9223 --lang=de"). These switches are only meaningful to the CHROMIUM_HTMLEDIT client. See STBL("!CHROMIUM_SWITCHES").

In BBj 22.13 and higher, the following BBj-specific switches can be specified in this string:

--bbj-save-password={save|never|ignore}

--bbj-update-password={update|ignore}

For more information, see: Passwords.

Return Value

This method returns the BBjHtmlEdit control.

Remarks

If the ID parameter is not specified, a control ID is assigned dynamically using getAvailableControlID().

If the x, y, width, and height parameters are not specified, they are all initialized to 0. This is typically for use with DWC windows that dynamically arrange their contents (window creation flag $00100000$).

If the initialization of a CHROMIUM_HTMLEDIT client fails, BBj logs the error, then tries again without any STBL("!CHROMIUM_DIR") and STBL("!CHROMIUM_SWITCHES") that might have been specified.
