 DELPHI DEVELOPER SUPPORT
Delphi 3 update and patch
Areas of concentration under: vcl
Area: vcl\additional controls\tchecklistbox Problem: OnClickCheck event is missing the Sender parameter. Area: vcl\additional controls\timage Problem: [TImage] If you set Stretch property True, Image won't be repainted at loading time. Area: vcl\additional controls\tmaskedit Problem: TMask class (Masks unit) cannot handle DBCS at all. Area: vcl\core vcl classes Problem: TMemoryStream.SetSize doesn't properly reset the stream position when then new size is less than the current stream position. Area: vcl\core vcl classes Problem: In Delphi 2.0 you could hide the TApplication window by calling ShowWindow(Application.Handle, SW_HIDE); but in D3 this no longer works and creates a pretty big problem for tray icon apps. TApplication.UpdateVisible gets called everytime a form is created, destroyed, shown or hidden so basically you can't hide the TApplication window. Area: vcl\core vcl classes Problem: TStrings.CommaText returns all items quoted. In 2.0, they are only quoted if they contain a space or quote. Area: vcl\system controls\tolecontainer Problem: Objects inserted into the TOleContainer overlap the bevel which really degrad its appearance. Area: vcl\thread support Problem: move SyncObj to Source\VCL Area: vcl\win95 controls\tcoolbar Problem: Coolbar crashes when AutoSize is true & at least one control on the form is aligned to client. Area: vcl\win95 controls\tcoolbar Problem: Bands appear different between designtime and run-time. Also, design time positioning is changed when toggling the FixedSize property while Vertical is True Area: vcl\win95 controls\tcoolbar Problem: ShowText=True is ignored at run-time if a band doesn't contain any components Area: vcl\win95 controls\tcoolbar Problem: Coolbar will crash application, if the Autosize and Align properties are changed at runtime. Area: vcl\win95 controls\tcoolbar Problem: When alignment of a coolbar is None, the Autosize property does not work -- the coolbar can still be re-sized. Area: vcl\win95 controls\tcoolbar Problem: Re-paint problem when changing the position of a coolbar. If Align is alNone, and the then changed to Top, Bottom, Left or RIght, part of the coolbar is not repainted correctly. Area: vcl\win95 controls\tdatetimepicker Problem: The datetimepicker when used as an AX does not fire Onclick events, and the date cannot be changed. The reason is that csReflector controlstyle was not used hence the notifications are not propagated out to the control. Area: vcl\win95 controls\timagelist Problem: Problem in TCustomImageList.ReplaceMasked routine in CONTROLS.PAS. This routine was broken in D2, and broken in a different way in D3. Using a dark colour scheme can make every colour transparent, so the glyphs on any buttons that use TCustomImageList (which include TSpeedButtons) become invisible. Altering the VCL Mask code by Adding Monochrome := True line and recompiling with the fixed CONTROLS.PAS solves the problem. Area: vcl\win95 controls\tlistview Problem: If the EditCaption method is called when the list view is not focused, the in-place editing does not take place Area: vcl\win95 controls\trichedit Problem: Alignment property for RichEdit component doesn't work on form design time. If you run the form, the string appears on specified position. Area: vcl\win95 controls\ttoolbar Problem: Buttons in TToolbar is not repainted propely when switched from disabled to enabled Area: vcl\win95 controls\ttoolbar Problem: If you use a bunch of grouped, tbsChecked ToolButtons and AllowAllUp is True, you can't make them all up by clicking on the buttons. Area: vcl\win95 controls\ttoolbar Problem: The TToolBar component creates an "List Index Out of Bounds (-1)" error if a TToolButton is dragged outside of the bounds of the control. Area: vcl\win95 controls\ttoolbar Problem: Put a TToolbar on a form, and add a few buttons. Insert a TLabel into the toolbar. The buttons' heights shrink to become the same as the TLabel. If anything changes height, it should be the TLabel which changes height to the toolbar buttons' height, and then changes its vertical layout to centered.
