6. Have a look at the tool bar to the left: here you can find all the control elements you can
place inside your form. They are represented as small icons. Move the mouse cursor
over the different icons to see the bubble help revealing their names. You should find an
icon showing the HALCON symbol named ÀÏÒÓÛØÖÐ. You guessed it! That is our
ActiveX control HALCON window.
7. Activate the ÀÏÒÓÛØÖÐ icon. Draw a rectangular region inside the form — make
sure it is approximately square. When releasing the mouse button the square area should
turn black.
8. Switch to the ÓÑÑÒÙØØÓÒ icon (looking like a brick) in the left tool bar. Draw
a button inside the form beside or below the HALCON window. Change the button’s
caption text to ÆÜØ in the properties box.
9. Now switch to ÄÐ in the tool bar and draw a longish rectangular area at the bottom
of the form. If you encounter placement difficulties due to lack of form space, you can
always resize the form to fit your needs.
10. Resize the form so that it fits around the before created items. Now you have the entire
GUI for your application ready to go and your screen should look similar to figure 3.1.
