CoolBar: how to save and restore the layout

i do not know how to change at runtime the layout from a Coolbar because the Coolbands do not have top or height properties. if i set the properties from toolbar - this of course does not work.

thanks for help

Hi

Manipulating Coolbars is a bit of a nuisance, and not as easy as most other Delphi controls.  Maybe Borland got bored???

Anyway, you have to send the coolbar messages to manipulate bands.  (See function TCoolBar.UpdateItem in ComCtrls.pas.)

Here is a very simple example.  This code puts the first 3 bands onto the 1st row (each with width = 75) and any more bands onto new rows by themselves.  (Add CommCtrl to your "uses" list.)

procedure TForm1.Button1Click(Sender: TObject);
var
    i: Integer;
    BandInfo: TReBarBandInfo;
begin
    // Delete all the bands!!
    for i := 0 to Coolbar1.Bands.Count - 1 do
        Coolbar1.Perform(RB_DELETEBAND, 0, 0);

    // Reinsert the bands as we want them.
    for i := 0 to Coolbar1.Bands.Count - 1 do
    begin
        FillChar(BandInfo, SizeOf(TReBarBandInfo), 0);
        BandInfo.cbSize := SizeOf(TReBarBandInfo);
        BandInfo.fMask := RBBIM_SIZE or RBBIM_CHILD or RBBIM_CHILDSIZE or RBBIM_STYLE;

        Coolbar1.Perform(RB_GETBANDINFO, i, Integer(@BandInfo));

        if (i > 2) then BandInfo.fStyle := BandInfo.fStyle or RBBS_BREAK;

        BandInfo.hwndChild := Coolbar1.Bands[i].Control.Handle;
        BandInfo.cx := 75;
        BandInfo.cxMinChild := Coolbar1.Bands[i].MinWidth;
        BandInfo.cyMinChild := Coolbar1.Bands[i].MinHeight;
        Coolbar1.Perform(RB_INSERTBAND, i, Integer(@BandInfo));
    end;
end;

This sample is a bit rough and ready.  I have inherited a new component from TCoolbar which allows you to manipulate bands better.  It works kind of like the Top & Height properties you were referring to.  I can e-mail it to you if you want...

Regards,
JB

Hi all

I have sent you both e-mail in this regard.  Unfortunately I cannot find the component I mentioned above, but I have e-mailed to both of you a sample which allows you to manipulate Coolbar bands.

Cheers,
JB
