- 6. • Ways ofArranging Components in GUI • Uses Container class setLayout() method 1. Absolute Positioning • Provides greatest level of control by setting setLayout method to null. But it can be tedious to set absolute positioning. • Methods like setSize, setLocation, and setBounds are used. 2. Layout Managers • FlowLayout • BorderLayout • GridLayout 3. Visual Programming in an IDE • Provides GUI design tool. • Supports drag and drop. Layout Managers Instructor: Tanzila Kehkashan 6
- 7. java.awt.FlowLayout • Default forjavax.swing.JPanel • Components are placed from left to right in order they are added. • Automatically places components onto next row, if row is full. • FlowLayout() • FlowLayout(int) // alignment Alignment Constants • FlowLayout.LEFT • FlowLayout.RIGHT • FlowLayout.CENTER (default) • void setAlignment(int)// alignment • int getAlignment() Layout Managers FlowLayout Instructor: Tanzila Kehkashan 7
- 8. java.awt.BorderLayout • Default forjavax.swing.JFrame • Arranges components in five regions • Places upto five components in a container one in each region. • Automatically displaces previous component, if component is already occupied in the position. • BorderLayout() • BorderLayout(int, int) // horizontal gap, vertical gap Regions • BorderLayout.NORTH • BorderLayout.SOUTH • BorderLayout.EAST • BorderLayout.WEST • BorderLayout.CENTER Layout Managers BorderLayout Instructor: Tanzila Kehkashan 8
- 9. java.awt.GridLayout • Divides containerinto a grid so that components can be placed in rows and columns. • Each component has same width and height. • GridLayout() • GridLayout(int, int) // rows, columns • GridLayout(int, int, int, int) // rows, columns, horizontal gap, vertical gap • int getColumns() • int getHgap() • int getRows() • int getVgap() • void setColumns(int cols) • void setHgap(int hgap) • void setRows(int rows) • void setVgap(int vgap) Layout Managers GridLayout Instructor: Tanzila Kehkashan 9
