When this event should be called in the component?

[pholon]

I want to free some memory when TsPageControl closing one tabsheet.

Can TsPageControl add a method “CloseActivePage”?

[pholon]

Just like tms.advPageCoutrol : OnCloseActivePage, CloseActivePage Method and so on.

[pholon]

sPageControl.pas

procedure TsPageControl.WndProc(var Message: TMessage);

WM_LBUTTONUP, WM_LBUTTONDOWN:

if Assigned(OnCloseBtnClick) then OnCloseBtnClick(Self, i, b, Act);

and

procedure TsPageControl.CloseClick(Sender: TObject);

if Assigned(OnCloseBtnClick) then OnCloseBtnClick(Self, TsTabBtn(Sender).Page.TabIndex, ToClose, Act);

OnCloseBtnClose Renamed OnClosePage, More appropriate.

if you add a method closePage(iIndex : Integer) to closing the, Just like TsPageControl.CloseClick. it More convenient.

sorry my bad english.

thanks

Closed page may be destroyed or just hidden,

How you think, this event should be called in both cases?

[pholon]

there is a menuitem with caption “CloseAllTabSheets” in mainmenu.

if this menuitem clicked then calling the method :

//code

procedure OnCloseAllTabsheets;

begin

while sPageControl1.PageCount 0 do

begin

sPageControl1.ActivePageIndex := 0;

try

sPageControl1.CloseActivePage; //!!!!!!! need this method or : sPageControl1.ClosePage(aPageIndex : Integer);

if iPageCount = sPageControl1.PageCount then //close error

Break;

except

on E : Exception do

begin

MessageBox(Handle, Pchar(E.Message), 'OK', MB_OK);

Break;

end;

end;

end;

end;

//code

thanks!

…….

So, an event is not needed? You want to have a procedure for a pages closing??

[pholon]

yes, I want to have a procedure for a pages closing. and when closing, calling OnCloseBtnClose

[Support]

But why you can't use standard ways for a page closing?

I will think about adding the OnClosePage event.
