TabVisible (C++)

Description

This example creates ten Tab Sheets and sets the captions to display PageIndex and TabIndex for each tab. Odd numbered tabs have their TabVisible property set off to demonstrate the effect on PageIndex vs. TabIndex. On the series of visible tabs, PageIndex will read 0, 2, 4, 6, 8, and TabIndex will read 0, 1, 2, 3, 4. PageIndex counts only visible tabs.

Code

__fastcall TForm1::TForm1(TComponent* Owner)
  : TForm(Owner)
{
  const TColor colorPalette[12] = { // not effective unless themes are disabled
	clRed, clGreen, clYellow, clBlue, clWhite, clFuchsia,
	clTeal, clNavy, clMaroon, clLime, clOlive, clPurple};
  PageControl1->MultiLine = true;
  for (int i = 0; i < 10; i++)
  {
	TTabSheet *page = new TTabSheet(this); // These tabsheets will be cleaned up by their owner (this).
	page->PageControl = PageControl1;
	page->TabVisible = (i % 2 == 0);
	page->Caption =
	  String(L"મઽૠ૪ PageIndex: ") + IntToStr(page->PageIndex) +
	  String(L" મઽૠ૪ TabIndex: ") + IntToStr(page->TabIndex);
	page->Brush->Color = colorPalette[i];
  }
}
