Hi Boki,

I've got a severe problem with anchored controls on a NxPageControl!

When I create some pages and put some NxControls on it and anchor them to all sides (with Anchors property) I see that only the activepage is resized properly when I resize the application in the TForm.OnCreate handler. The other controls on non visible pages are not resized properly.

The NxPageControl is alClient aligned to the Form and has a Margin of 4.

Hello Wim,

Maybe it is not possible different, because I am hidding innactive pages and this maybe block anchors

I will see what I can do here. If you have any suggestion , please tell me.

Best regards

Hello Wim,

I suggest disabling next line in NxCustomNotebook.SetActivePage:

CODE

  { old page }
  if Assigned(FActivePage) then
  begin
//    FActivePage.Hide; { page is not hidden in design-time } <------ comment this line
    FActivePage.DoHide; { event }
    AOldIndex := FActivePage.PageIndex;
  end else AOldIndex := -1;

But, I am not sure is this will cause some other problems, like tab going into hidden page and similar.

I will test it more, if you can please tell me if you spot some anomaly.

Best regards

Thanks for looking into it.

Strangely enough is resizing at designtime ok. It only happens at runtime (even if i do not set the bounds of the app at startup, controls just don't anchor on certain sides as if the anchor property isn't loaded correctly).

Hi Boki,

I now can get 3 of the 6 tabs to align properly. The rest of the tabs and their controls refuse to anchor(or only do so horizontally). It's the first two and the active Tabsheet one at designtime (or the last one i edited, not sure about that).

Thanks for looking into it.

Hello Wim,

In run-time, page can't be hidden and this is why all work fine. But in run-time, if I don't hide page (TNxTabSheet), user will be able to Tab troughs 2 pages even one is inactive.

Maybe I can try to call resize of all inactive pages in WM_SIZE message.

Hi Boki,

I hope you find a good solution. For now (due to pressure on the project) I hardcoded the resizing.

Hello Wim,

Can you please tell me how do you do this? Do you have force anchors?

I have try to not hide page (commenting line in sample which I post in previous posts), but Tabs are moving trough visible and invisible pages then

I will need to somehow disable inactive pages instead hiding it.

Best regards

Update: It seems that each page must be opened at least once that all works.

Maybe there is a hope for this problem

Hello Wim,

Change next procedure in NxPageControl.pas file:

CODE

procedure TNxTabSheet.SetParentComponent(Value: TComponent);
begin
  inherited;
  if Value is TNxCustomNotebook then
  begin
    FPageControl := TNxCustomNotebook(Value);
    if Self <> FPageControl.ActivePage then Hide;
    FPageControl.FPageList.Add(Self);
    SetBounds(0, 0, FPageControl.ClientWidth, FPageControl.ClientHeight); // <------ new line
  end;
end;

Please tell me how it works now.

Best regards

Hi Boki,

Hurray it seems to work properly (i removed the first fix and applied the 2nd one). Keep testing it a bit more please.

What a single line of code can make a difference!
