I'm using Delphi XE6 on top of Windows 2012 R2, and trying to create applications with toolbars. I'm however experiencing problems with the compiled application having a vertical superfluous bar at the left hand side of any Separators I might add.
This problem is described in both This Question and This Other Question, however I am not trying to use any other fancy controls - I am solely using the "New Button" and "New Separator" to add items. I have nonetheless tried the suggested fixes to no avail.
My sample application has been created as follows:
New VCL Forms Application
Add TToolBar
Select ToolBar1
Right Click, Select "New Button"
Right Click, Select "New Button"
Right Click, Select "New Separator"
Right Click, Select "New Button"
Run
This is what the application looks like
I have tried changing every potentially applicable property of the TToolBar itself (including setting Transparent to False), as well as the ToolBar3 (which is set to tbsSeparator), but I cannot seem to get rid of this vertical bar. I have also tried to add a TXPManifest to the form, but this made no difference.
The only thing that does seem to make a difference is if I set the Separator Visible property to False - the line disappears, but so does the Separator, so this isn't any help.
The issue I'm experiencing is also described in This thread, and I can assure the readers that I've not made any changes to the width of the Separator - it's all default.
Does anybody have any suggestions on how I can fix this?
For what it's worth - my Delphi Form is like this - you can see that I'm not using any fancy controls other than the supported ones:
object Form1: TForm1
Left = 0
Top = 0
Caption = 'Form1'
ClientHeight = 112
ClientWidth = 382
Color = clBtnFace
Font.Charset = DEFAULT_CHARSET
Font.Color = clWindowText
Font.Height = -11
Font.Name = 'Tahoma'
Font.Style = []
OldCreateOrder = False
PixelsPerInch = 96
TextHeight = 13
object ToolBar1: TToolBar
Left = 0
Top = 0
Width = 382
Height = 29
Caption = 'ToolBar1'
TabOrder = 0
Transparent = False
object ToolButton1: TToolButton
Left = 0
Top = 0
Caption = 'ToolButton1'
ImageIndex = 0
end
object ToolButton2: TToolButton
Left = 23
Top = 0
Caption = 'ToolButton2'
ImageIndex = 1
end
object ToolButton3: TToolButton
Left = 46
Top = 0
Width = 8
Caption = 'ToolButton3'
ImageIndex = 2
Style = tbsSeparator
end
object ToolButton4: TToolButton
Left = 54
Top = 0
Caption = 'ToolButton4'
ImageIndex = 3
end
end
object XPManifest1: TXPManifest
Left = 40
Top = 48
end
end

As the TToolbar is a wrapper of Microsoft Windows Rebar32 Control, it looks exactly the same as a normal Windows application does. Why not remove these separators, so that you will not see them anymore.
