Adding toolbars to the designer window

rbuser

Using D7, RB9, Win2000

Hi

We have just upgraded to RB9 and are trying to get our toolbars to work. We
use the following code

ToolbarManager := TppDesignerWindow(ReportDesigner.Form).ToolbarManager;
StylingToolbar := ToolbarManager.NewToolbar('Styling');

StyleSelectionComboBox := TComboBox.Create(StylingToolbar);
... more initializations ...

We used to have it in TppDesigner.OnCreate (using RB7), but the
ToolbarManager is here nil. It is not accessible until
TppDesigner.OnActivate because it isn't created before
TppDesignerWindow.WMShowWindow.
Is this an error?

It also seems that TppToolbarManager.NewToolbar is not calling the private
method TppToolbarManager.BuildPopupMenu that is called from
TppToolbarManager.AddToolbar.
Is this intended?

Kind Regards
Steffen

Looked a bit more into the case.

I get an access violation when i change any of the components in the
TppDesigner.ShowComponents list to false. Traced the error to the method
TppDesigner.CreateDesignerWindow where the following code is executed:

if (FShowComponents <> cAllShowComponents) then
FDesignerWindow.ComponentClasses := FComponentClasses;

This calls the TppDesignerWindow.GetComponentClasses that uses the
TppToolbarManager, that is not yet initialized causing the access violation.

Hope you will fix this soon.

Kind Regards
Steffen

1. There is an RB 9.0 patch available that fixes the
TppDesigner.ShowComponents feature. Email support@digital-metaphors.com and
request the patch.

2. The timing of the ToolbarManager/Toolbar creation and initialization has
changed. The underlying toolbar architecture is now relying on Delphi's
built-in toolbar functionality rather than the Toolbar 97 that we were using
before. We had to make some changes to the timing in order to get things to
work properly.

Try using the Designer.OnShow event to create your custom toolbars.

3. I am not sure whether that is intended or not (I wrote the code long
ago). It was not designed to accomodate adding custom toolbars, but I think
it should work. For now, try using AddToolbar.
