show/hide menu

which menu : a system menu in the child window or a menubar ?

'cause you can change/modify menu , you could disable/enable a menu as well

see my web site for examples ( beginners for instance, /* don't like word newbie :-) */ )

I am agree with JPM: you can hide/show (in child) every
menu, becouse usually menu "connected" with client,
and you can easy get you client window,something as:
GetApplication->GetMainWindow()

i want to hide all menus, because child window has a function, that has to work as fast as possible until user presses 'stop' button.

There is a line in that fuction : GetApplication()->PumpWaitingMessages(). But the problem is, that when menu is selected and the coresponding submenu pops out and the function stops (it continues after pressing releasing menu).

I want menu to be invisible while function is running.

I read in help about SetMenu(HMENU newMenu) function, that if newMenu is 0, the window's current menu is removed. So have tried to do like this:

GetApplication()->GetMainWindow()->SetMenu(0);

but this doesn't work.

I have solved this problem now by calling that function in a separate thread and everything works fine now, but now the child window has to disable all menu items, how to do that not writing all menu items in responce table?

using another thread is a good idea.

for your last question, I guess there are differents ways ( I ain't try them out though )

-> there is EV_WM_ENTERIDLE
with void EvEnterIdle(uint source, HWND hwndDlg)
if source gets MSGF_MENU, then menu becomes inactive.

->you could use a SendMessage command in a loop with menuId to disabling menu.

->or a loop using
bool EnableMenuItem(uint idItem, MF_DISABLED);

-> or bool RemoveMenu(uint idItem, uint flags);
Removes the menu item from the menu but does not delete it if it is a submenu.

->or you could use a SetMenu(NULL) to change menu to a new one which is 0.

1.I want menu to be invisible while function is running.
THis is not standart and notr so estethic. Better, I think,
make all menu disabled. For this I use simple
EV_COMMAND_ENABLE in Responce Table:

EV_COMMAND_ENABLE(CM_HELPABOUT, CmFileOpenEnable),
and
void TApp::CmFileOpenEnable(TCommandEnabler& tce)
{
TGidonMDIClient* mdiClient = TYPESAFE_DOWNCAST(GetMainWindow()->GetClientWindow(), TGidonMDIClient);
//exists client, and not error?
if (mdiClient && !mdiClient->bStop)
tce.Enable(true);
else
tce.Enable(false);
}
where bStop =false during working you function
2.>>how to do that not writing all menu items
in responce table?
Must be Responce table and must be
EV_COMMAND_ENABLE/EV_COMMAND lines.
Plus some menu items "linked" to Client, some to
apps, some to chield. Why it is problem??

the problem is that 'stop' is private to child an app can't access it.

So i guess the easiest way to solve this problem is to make 'stop' accessable to app so it can disable all menu items when function is running.

>>to make 'stop' accessable to app
Other simple solution use some function , say
bool GetStop (){return stop}
and change code to something
TGidonMDIChield* mdiChield = TYPESAFE_DOWNCAST(mdiClient->()->GetActiveChield(), TGidonMDIChield);
bool bStop = mdiChield->GetStop();

Alex is right with command enable using RESPONSE_TABLE : it's the common way.
but mykapa, you said not to using RESPONSE TABLE, right ?

and what about friend class to access private data?

03.18.2001 at 10:14PM PST, ID: 5939932

i think i'll do as Alex proposed, it is simple

i don't want to use responce table, because adding new menu items will be hard... i'll have to check for child's state in every item. So i wanted, that child will disable whole menu (if he does that in his responce table, then after modifying app i have to change all children classes).

And what about system menu? I want to disable it too.
Close command isn't disabled, but it doesn't work while child executes that function (child returns false in CanClose)

>>I want to disable it too
For disable Close Button, make something as next in
you Client
class TMyFrame : public TDecoratedMDIFrame
{
public:
TMyFrame (TWindow* parent, const char * title, TWindow* client, bool
track_menu, TModule* module)
: TDecoratedMDIFrame (parent,title,client,module)
{
}
void SetupWindow ()
{
TDecoratedMDIFrame::SetupWindow();
SystemMenu.EnableMenuItem (SC_CLOSE, MF_GRAYED);
EnableWindow (false);
}
};

why not disabling menu just when the function from the chlid menu response table is called?
the first line you disable...the last one you restore or when user hits stop.

i'd like to do like this. But how?
