TreeNode::NodeFont Property
.NET Framework (current version)
Gets or sets the font that is used to display the text on the tree node label.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The following code example changes the size of NodeFont to the specified size and adjusts the ItemHeight of the tree node's parent TreeView control. This example requires that you have a Form with a TreeView control that contains a collection of TreeNode objects, and a ComboBox that contains font sizes.
private: void Button1_Click( Object^ /*sender*/, EventArgs^ /*e*/ ) { myTreeView->ItemHeight = 5; myTreeView->SelectedNode->NodeFont = gcnew System::Drawing::Font( "Arial",5 ); // Get the font size from combobox. String^ selectedString = myComboBox->SelectedItem->ToString(); int myNodeFontSize = Int32::Parse( selectedString ); // Set the font of root node. myTreeView->SelectedNode->NodeFont = gcnew System::Drawing::Font( "Arial",(float)myNodeFontSize ); for ( int i = 0; i < myTreeView->Nodes[ 0 ]->Nodes->Count; i++ ) { // Set the font of child nodes. myTreeView->Nodes[ 0 ]->Nodes[ i ]->NodeFont = gcnew System::Drawing::Font( "Arial",(float)myNodeFontSize ); } // Get the bounds of the tree node. Rectangle myRectangle = myTreeView->SelectedNode->Bounds; int myNodeHeight = myRectangle.Height; if ( myNodeHeight < myNodeFontSize ) { myNodeHeight = myNodeFontSize; } myTreeView->ItemHeight = myNodeHeight + 4; }
