Marek,

I just have an idea. Can it be done with a window with number or command buttons? Here arrow keys will work.

With best regards.

jucar_es presented Such an idea.
But, a menu like MainMenu or DropDown Menu is on my mind...

I'm studying sources of hmg to build my own menu, but it's going hard :D

I think, I've reached effect, which satisfies me!
There are some things to do, yet, but I want to place working sample now.
Problem is how to compute height of component to disable appearing of scrollbar.
Sample works fine for more than 4 options i menu.

I've changed some sources from hmg to produce my own component ACHOICEMENU
Please, test and write your opinions, I'll be greatful!
So, happy testing!
Marek

Nice work Marek.

Modified Listbox without vertical scroll bar if number of items are less is good. Thanks for sharing. I will use it. :)
East or West HMG is the Best.
South or North HMG is worth.
...the possibilities are endless.

If you change line:

Code: Select all

int Style = WS_CHILD | WS_VSCROLL |  LBS_NOTIFY | LBS_NOINTEGRALHEIGHT ;
to line:

Code: Select all

int Style = WS_CHILD | LBS_NOTIFY | LBS_NOINTEGRALHEIGHT ;
vertical scrollbar never appears.

thanks for testing.
Marek


Ps. I've tried to use procedures to create menu like a system menu, notify menu, but, I can't find how to control fontsize and colors of menu.

So, modified listbox seems to be the best way to build Achoice.

Dear BPD,

You can change the lines referring MSGMINIGUIERROR into MsgStop()

Hi,

Regarding achoice, I think, grid control can be used for AChoice like interface without any buttons at all and it can be combine with windows TOPMOST, MODAL. But sorry I don't have a sample to give, three days ago it is also my problem when I realized that Achoice can be achieved by Grid without sweat. IMHO.

Danny

Hello Marek and everyone,

Here is my implementation of ACHOICE in HMG using grid control. The only problem is that it nearly look likes the ACHOICE of the old days.

Caveats:
1. Grid control height and width must be larger than the height of the window, frmAchoice in this regard so that the scroll bars is not visible.
2. If you want the horizontal and or vertical scroll bar, then adjust the dimentsion calculation.
3. I'm still using HMG 3.8 (out of pure laziness to back-up and test).
4. You can build the sample using the build.bat


Code: Select all
