By default, the Mode property exSplitBarAuto, which indicates that the split bar's mode is determines by its size as:

• if the width of the split bar is greater or equal than its height, the Mode property is exSplitBarVert
• if the width of the split bar is less than its height, the Mode property is exSplitBarHorz

Any of the following properties can be used to anchor controls/components/objects to the left/top/right/bottom sides of the split bar:

• ObjectsLT property indicates the object(s) to be updated in the left/top part of the split bar
• AddObjectLT method adds a new object to be updated in the left/top part of the split bar
• ObjectsLT property indicates the object(s) to be updated in the right/bottom part of the split bar
• AddObjectRB method adds a new object to be updated in the right/bottom part of the split bar

The LimitRB property specifies the expression that determines the limit to drag the splitter to right/bottom side of its container. The LimitLT property specifies the expression that determines the limit to drag the splitter to left/top side of its container.

Here's the steps you need to follow in order to use the eXSplitBar control:

• Insert the eXSplitBar library/reference to your project
• Place eXSplitBar control to your form/dialog/window
• Specify the objects in the left/top and right/bottom parts of the split bar, using the ObjectsLT / ObjectsRB or AddObjectLT / AddObjectRB available at runtime.

For instance, let's say we have the following layout:

so we have two split bars ( horizontal and vertical ), and three buttons/commands. One splitter should resizes the left-most button, and the rest, and the vertical split bar show resize the top-most button and the bellow one.

In

• C# for /NET Assembly
• Microsoft Office ( Access, Excel, Word )
• Visual Basic 6
• Visual Basic for /NET Assembly
• Visual FoxPro

you can select the split bar in design mode, and specify the objects in the left/top and right/bottom parts of the split bar as in the following screen shot, using the ObjectsLT and ObjectsRB properties:

In 

• C++ Builder
• C# for /COM on /NET Framework
• Delphi
• Visual Basic for /COM on /NET Framework
• Visual C++

you need to use the AddObjectLT and AddObjectRB methods as in the following samples.

C++ Builder :

SplitBar1->AddObjectLT(TVariant(Button1->Handle));
SplitBar1->AddObjectRB(TVariant(Button2->Handle));
SplitBar1->AddObjectRB(TVariant(SplitBar2->DefaultInterface));
SplitBar1->AddObjectRB(TVariant(Button3->Handle));

C# for /COM on /NET Framework :

axSplitBar1.AddObjectLT(button1);
axSplitBar1.AddObjectRB(button2);
axSplitBar1.AddObjectRB(axSplitBar2);
axSplitBar1.AddObjectRB(button3);

Delphi :

with SplitBar1 do
begin
	AddObjectLT(Button1.Handle);
	AddObjectRB(Button2.Handle);
	AddObjectRB(SplitBar2.DefaultInterface);
	AddObjectRB(Button3.Handle);
end

Visual Basic for /COM on /NET Framework:

With AxSplitBar1
	.AddObjectLT(Button1)
	.AddObjectRB(Button2)
	.AddObjectRB(AxSplitBar2)
	.AddObjectRB(Button3)
End With

Visual C++:

EXSPLITBARLib::ISplitBarPtr spSplitBar1 = GetDlgItem(IDC_SPLITBAR1)->GetControlUnknown();
spSplitBar1->AddObjectLT( (long)::GetDlgItem( m_hWnd, IDC_BUTTON1 ) );
spSplitBar1->AddObjectRB( (long)::GetDlgItem( m_hWnd, IDC_BUTTON2 ) );
spSplitBar1->AddObjectRB( GetDlgItem(IDC_SPLITBAR2)->GetControlUnknown() );
spSplitBar1->AddObjectRB( (long)::GetDlgItem( m_hWnd, IDC_BUTTON3 ) );
