4D Write Pro has a feature in v16R5 to insert headers. Initially, when a 4D Write Pro object is created, the header is not initialized. Here is a utility method that will detect if the Write Pro object has the header present:

// ---------------------------------------------------------------------- // Name: WP_HEADER_PRESENT // Description: Method will determine if the 4D Write Pro object has a header // // Parameters: // $1 (POINTER) - Write Pro object // // Output: // $0 (BOOLEAN) - True - Contains a header, False - No header // ---------------------------------------------------------------------- C_POINTER($1;$writeProObj) C_BOOLEAN($0) C_TEXT($writeProVar) C_LONGINT($pos) $writeProObj:=$1 WP EXPORT VARIABLE($writeProObj->;$writeProVar;wk web page html 4D) $pos:=Position("div.section1Header";$writeProVar) If ($pos>0)   $0:=True Else   $0:=False End if

Example #1 - No header set

C_LONGINT($status) $status:=WP_HEADER_PRESENT(->WriteProArea) // False

Example #2 - Having a header with no text

$status:=WP_HEADER_PRESENT(->WriteProArea) // True

Note: Clicking on the header area will initialize the object to contain the header placeholder.


Example #3 - Having a header with text

$status:=WP_HEADER_PRESENT(->WriteProArea) // True
