Blur
Forms, interaction, input
Description
Clears Widget focus of a TPDFlibFormSession after finishing the active edit
When a Widget has focus, its active edit is committed or cancelled first, the /Bl blur action is dispatched for the focused Widget and only then is focus cleared
With no Widget focused but an edit active, the call only commits or cancels that edit and returns the corresponding result
A vetoed /Bl keeps the current focus and returns 0
Declaration
function Blur(CommitCurrent: Boolean = True): Integer;Parameters
| CommitCurrent | True commits the active edit before blurring, False cancels it |
|---|
Return value
Returns 1 when focus was cleared or nothing needed blurring, otherwise 0 when the call was reentrant, the commit failed or the /Bl action was vetoed
