This command is not thread-safe, it cannot be used in preemptive code.
Description
The WP SET FRAME command sets the cursor into the frame designated by frameSelector and optionally, textBoxID, in the 4D Write Pro wpArea area.
If you pass the optional * parameter, you indicate that wpArea is a form object name (string). If you do not pass this parameter, you indicate that wpArea is a 4D Write Pro object variable or field.
Note: This command can only be used if the wpArea is associated with a form object (i.e. it is displayed in the current form/page).
You can pass in frameSelector one of the following constants from the 4D Write Pro Constants theme:
| Constant | Type | Value | Comment |
|---|---|---|---|
| wk body | Longint | 0 | Body frame of the section |
| wk current page footer | Longint | 2 | |
| wk current page header | Longint | 1 | |
| wk current section default footer | Longint | 10 | Default footer of the section (available only if there is no active subsection footer) |
| wk current section default header | Longint | 9 | Default header of the section (available only if there is no active subsection header) |
| wk current section first footer | Longint | 4 | Footer of the first page of the section |
| wk current section first header | Longint | 3 | Header of the first page of the section |
| wk current section left footer | Longint | 6 | Footer of the left page(s) of the section |
| wk current section left header | Longint | 5 | Header of the left page(s) of the section |
| wk current section right footer | Longint | 8 | Footer of the right page(s) of the section |
| wk current section right header | Longint | 7 | Header of the right page(s) of the section |
| wk text box | Longint | 11 | Text box |
- If wk current page header or wk current page footer is passed in frameSelector, WP SET FRAME will give focus to the first selected page header or footer, no matter the sub-section type (if it does not contain any header or footer, the command will do nothing).
- If any of the wk current section[...] constants are passed in frameSelector, WP SET FRAME will give focus to the specified sub-section header or footer of the first selected section (if it does not contain any header or footer, the command will do nothing).
- WP SET FRAME will do nothing if the frameSelector frame does not exist for the selection section (for example, wk current section left header when there is no distinction between left and right pages in wpArea).
If frameSelector = wk text box, you must pass the textBoxID parameter with the id of the text box in which to set the focus. In this case, if textBoxID is omitted or if there is no text box with the specified id or if there is no page corresponding to the anchor conditions of the text box, the command does nothing. The textBoxID parameter is ignored if frameSelector # wk text box.
Example
You want to set the cursor to the left footer of the current section:
WP SET FRAME(*;"WPArea";wk current section left footer)
