This demo builds a widget application that uses at least one instance of each type of widget available in IDL.
Select "Quit" to close the "Widgets" application.
Select "About Widgets" to display this text.
The following widgets are included in the widget demo application:
Select "Shaded", "Wire", or "Lego solid" from the list to change the appearance of the surface displayed in the draw widget.
Select an item in the list to change the color of the surface displayed in the draw widget. The "Texture Map" option displays an image draped on the surface using the TEXTURE_MAP property of the surface. The color values of the image are based on the data value of the surface and a color table.
Change the position of the sliders to rotate the surface displayed in the draw widget around any one of the three axes. Note that the surface can also be rotated by dragging the left mouse button within the draw widget.
Click in the text field and use normal editing procedures to change the text.
Click on the "Message Popup" button to display a modal dialog message window. Click "OK" to dismiss the dialog.
The table widget displays the values of each element in the data array that is rendered in the draw widget.
You can edit the values in the table widget by clicking in a table cell, deleting the existing value, and entering a new value. Notice how the surface displayed in the draw widget changes as you alter values in the draw widget.
A shaded surface rendering of the data shown in the table widget is displayed in the draw widget. Most of the widget controls discussed above affect the look of the displayed surface. In addition, you can rotate the surface directly by positioning the mouse in the draw widget, holding down the left mouse button, and dragging the mouse. Notice that the values of the rotation sliders are updated as you rotate the surface interactively.
