Selection behavior for a container control in details view
Jim Moe
I have a container control in the details view, say for a folder that
shows a directory listing. I can select a record, then use sh+dn (shift +
down-arrow keys) to select more records; the equivalent of ctrl+mouseclick
or mouse-drag across multiple records.
If I then delete the record(s), the next record has only the
CRA_CURSORED emphasis but because no record is actually selected
(CRA_SELECTED), sh+dn does not work to select more records.
This is the default behavior.
In PMMail when a record (a message) is selected and deleted as described
above, a further action is taken by the code to select another record for
further operations by setting the CRA_SELECTED and CRA_CURSORED emphasis
attributes (with CM_SETRECORDEMPHASIS) to the next record after the
deleted one (or previous if it was the last record in the display).
This, unfortunately, is not the same as a mouse click to select a
record, or using just the Down arrow key to move to another record.
Entering the sh+dn keys has no effect, i.e., no further records are
selected even though the current record shows as selected/cursored.
It acts the same as the default behavior even though a record has been
explicitly selected.
I have tried sending the WM_BUTTON1CLICK message (WinSendMsg()) to the
record; the returns code indicates the message was ignored. I have tried
clearing first then setting the emphasis to no effect.
Has anyone else experienced this behavior?
And found a solution that allows the sh+dn to function after removing a
record?
