ListBox
• Let’s have the following small project …
ListBox
ListBox - SelectionMode
• One:– Can only choose one at a time
ListBox - SelectionMode
• MultiSimple: – No ctrl needed!
• MultiExtended:– ctrl needed when selecting more that one– Auto select changing
ListBox
ListBox - Coding
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++?
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();
}

• When changing the course …
CheckBox
CheckBox
• CheckBoxes– Set of non-connected controls– Can choose one or more “checkBox”
CheckBoxprivate: 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” );
}
}

CheckBoxprivate: System::Void button1_Click(System::Object^ sender,

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

• Hierarchy …– System::Object
System::MarshalByRefObjectSystem.ComponentModel::ComponentSystem.Windows.Forms::ControlSystem.Windows.Forms::ListControlSystem.Windows.Forms::ListBoxSystem.Windows.Forms::CheckedListBox
CheckedListBox
• Let’s have the following code …
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (checkedListBox1->SelectedIndex == 1 )
{
textBox1->Text = "WOOOW";
}
}
Why?!
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";
}
}
CheckedListBox
• So, we do this:
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (checkedListBox1->GetItemChecked(1) == true)
{
textBox1->Text = "WoW ";
}
}
CheckedListBox
• Now, let’s see this: private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
checkedListBox1->Items->Add("Spanish");
}
CheckedListBox
• And ofcourse, we can do this! private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
checkedListBox1->Items->Add(textBox1->Text);
}
CheckedListBox
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (checkedListBox1->Items[0]->ToString() == "English")
{
textBox1->Text = "WoW ";
}
}
CheckedListBox
RadioButton
RadioButton
• “Radio button”s– Set of related “item”s– Can choose only one “at a time”
RadioButton
• Only one can be chosen at a time
RadioButtonprivate: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e)
{
if (radioButton1->Checked == true )
MessageBox::Show("I wanna drink some water");
}
RadioButton
• So, how to break the restriction and select more than one radioButton?There’s sth called the “GroupBox” from “Containers” section.
GroupBox
GroupBox
GroupBox
• Now, we can choose more than one RadioButton• But we can only choose one RadioButton from “each”
GroupBox.
That’s it for today!
