TOPMOST

Post by **Jimmy** » Sat Nov 05, 2022 5:57 am

hi,

i want to create a Window which are "on TOP" of all other and will "stay" like MsgInfo()

---

in Help

Dialog
<nStyle> An optional DialogBox style.
There are several samples in the SAMPLES\ subdirectory showing you how to manipulate this value.

Windows:
<nStyle> A numeric value which indicates a special API style. [ Just for advanced FiveWin users.]

for "what" i have to search in \Sample Folder

i do found "STYLE" Constant Sample for almost every other Control but not for Dialog or Window

---

there is Constant WS_EX_TOPMOST which can change Style but it have no Effect when use

Code: Select all | Expand

STYLE WS_EX_TOPMOST

i also found this CODE

Code: Select all | Expand

    SetWindowPos( oObj:hWnd, HWND_TOPMOST  ,;
                  oObj:nTop, oObj:nLeft    ,;
                  oObj:nWidth, oObj:nHeight )

which i can use at INIT

is there another "easy" Way which i do not know

under HMG i "just" have to use Keyword TOPMOST

i also found this CODE
Code:
SetWindowPos( oObj:hWnd, HWND_TOPMOST ,;
oObj:nTop, oObj:nLeft ,;
oObj:nWidth, oObj:nHeight )

which i can use at INIT

Is this working as expected?

Can this be useful?

NO.
it will come to foreground but User can click on "MAIN" so it will "disappear" behind

Try this:

Code: Select all | Expand

FUNCTION ONTOP( oWnd )

    SETWINDOWPOS( oWnd:hWnd, -1, 0, 0, 0, 0, 3 )

    RETURN NIL
