18. ListBox
• Let’s have the following small project …

19. ListBox

20. ListBox - SelectionMode
• One:
– Can only choose one at a time

21. ListBox - SelectionMode
• MultiSimple:
– No ctrl needed!
• MultiExtended:
– ctrl needed when selecting more that one
– Auto select changing

22. ListBox

23. ListBox - Coding

24. private: System::Void listBox1_SelectedIndexChanged(System::Object^
sender, System::EventArgs^ e)
{
if (listBox1->SelectedIndex == 0)
{
textBox1->Text = "C++ Course is a course about c++!:D";
}
}
What’s will happen now?
What will happen when selecting another option after selecting C++?

25. ListBox - Coding
• It’s a runtime error if selecting nothing and then pressing
button2. Otherwise it works properly.
private: System::Void button2_Click(System::Object^ sender,
System::EventArgs^ e)
{
textBox1->Text =listBox1->SelectedItem->ToString();
}

26. ListBox - Coding
• When changing the course …

27. CheckBox

28. CheckBox
• CheckBoxes
– Set of non-connected controls
– Can choose one or more “checkBox”

29. CheckBox
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (checkBox1->Checked == true )
{
MessageBox::Show("You chose " + checkBox1->Text );
}
}
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (checkBox1->Checked == true )
{
MessageBox::Show("You chose " + “English” );
}
}
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (checkBox1->Checked == true )
{
MessageBox::Show("You chose English” );
}
}

30. CheckBox

31. CheckBox
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (checkBox1->Checked == true )
{
MessageBox::Show("You chose " + sender->ToString() );
}
}

32. CheckBox
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (checkBox1->Checked == true )
{
MessageBox::Show("You chose " + e->ToString() );
}
}

33. CheckedListBox

34. CheckedListBox

35. CheckedListBox
• Set of connected “checkBox”es

36. CheckedListBox

37. CheckedListBox

38. CheckedListBox

39. CheckedListBox

40. CheckedListBox
• Hierarchy …
– System::Object
System::MarshalByRefObject
System.ComponentModel::Component
System.Windows.Forms::Control
System.Windows.Forms::ListControl
System.Windows.Forms::ListBox
System.Windows.Forms::CheckedListBox

41. CheckedListBox
• Let’s have the following code …
private: System::Void button1_Click(System::Object^
System::EventArgs^ e)
{
if (checkedListBox1->SelectedIndex == 1 )
{
textBox1->Text = "WOOOW";
}
}
sender,

45. Why?!

46. CheckedListBox
• The same story goes with this:
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (checkedListBox1->SelectedItem == "French" )
{
textBox1->Text = "WOOOW";
}
}

47. CheckedListBox
• So, we do this:
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (checkedListBox1->GetItemChecked(1) == true)
{
textBox1->Text = "WoW ";
}
}

49. CheckedListBox
• Now, let’s see this:
private: System::Void button1_Click(System::Object^
System::EventArgs^ e)
{
checkedListBox1->Items->Add("Spanish");
}
sender,

51. CheckedListBox
• And ofcourse, we can do this!
private: System::Void button1_Click(System::Object^
System::EventArgs^ e)
{
checkedListBox1->Items->Add(textBox1->Text);
}
sender,

52. CheckedListBox
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (checkedListBox1->Items[0]->ToString() == "English")
{
textBox1->Text = "WoW ";
}
}

53. CheckedListBox

54. RadioButton

56. RadioButton
• “Radio button”s
– Set of related “item”s
– Can choose only one “at a time”

57. RadioButton
• Only one can be chosen at a time

58. RadioButton
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (radioButton1->Checked == true )
MessageBox::Show("I wanna drink some water");
}

59. RadioButton
• So, how to break the restriction and select more than one
radioButton?
There’s sth called the “GroupBox” from “Containers” section.

60. GroupBox

61. GroupBox

62. GroupBox
• Now, we can choose more than one RadioButton
• But we can only choose one RadioButton from “each”
GroupBox.

63. That’s it for today!
