Constructor & Destructor Documentation

◆ TGTableLayout() [1/2]

TGTableLayout::TGTableLayout ( const TGTableLayout )
private

◆ TGTableLayout() [2/2]

TGTableLayout::TGTableLayout ( TGCompositeFrame main,
UInt_t  nrows,
UInt_t  ncols,
Bool_t  homogeneous = kFALSE,
Int_t  sep = 0,
Int_t  hints = 0 
)

TGTableLayout constructor.

Note:

  • Number of rows first, number of Columns second
  • homogeneous == true means all table cells are the same size, set by the widest and the highest child frame.
  • s gives the amount of separation in pixels between cells
  • h are the hints, see TGTableLayoutHints.

Definition at line 94 of file TGTableLayout.cxx.

◆ ~TGTableLayout()

TGTableLayout::~TGTableLayout ( )
virtual

TGTableLayout constructor.

Definition at line 111 of file TGTableLayout.cxx.

Member Function Documentation

◆ CheckSanity()

void TGTableLayout::CheckSanity ( )
protected

Sanity check various values.

◆ FindRowColSizes()

void TGTableLayout::FindRowColSizes ( )
protected

Find the sizes of rows and columns needed to statisfy children's layout policies.

void TGTableLayout::FindRowColSizesHomogeneous ( )
protected

If the table is homogeneous make sure all col/rows are same size as biggest col/row.

Definition at line 186 of file TGTableLayout.cxx.

◆ FindRowColSizesInit()

void TGTableLayout::FindRowColSizesInit ( )
protected

Initialize values needed to determine the size of rows and columns.

◆ GetDefaultSize()

TGDimension TGTableLayout::GetDefaultSize ( ) const
virtual

Return default dimension of the table layout.

Implements TGLayoutManager.

Definition at line 641 of file TGTableLayout.cxx.

◆ Layout()

void TGTableLayout::Layout ( )
virtual

Make a table layout of all frames in the list.

Implements TGLayoutManager.

Definition at line 553 of file TGTableLayout.cxx.

◆ operator=()

TGTableLayout& TGTableLayout::operator= ( const TGTableLayout )
private

◆ SavePrimitive()

void TGTableLayout::SavePrimitive ( std::ostream &  out,
Option_t option = "" 
)
virtual

Save a primitive as a C++ statement(s) on output stream "out".

Reimplemented from TObject.

Definition at line 738 of file TGTableLayout.cxx.

◆ SetRowColResize()

void TGTableLayout::SetRowColResize ( UInt_t  real_size,
UInt_t  nthings,
TableData_t thing,
Bool_t  homogeneous 
)
staticprotected

If main frame is bigger or smaller than all children, expand/shrink to fill.

This is symmetric under row<-->col switching so it is abstracted out to a normal function to save typing.

Definition at line 266 of file TGTableLayout.cxx.

◆ SetRowColSizes()

void TGTableLayout::SetRowColSizes ( )
protected

This gets the new sizes needed to fit the table to the parent frame.

To be called after FindRowColSizes.

Definition at line 346 of file TGTableLayout.cxx.

◆ SetRowColSizesInit()

void TGTableLayout::SetRowColSizesInit ( )
protected

Initialize rows/cols.

By default they do not expand and they do shrink. What the children want determine what the rows/cols do.

Definition at line 361 of file TGTableLayout.cxx.
