3. Change the Stretch property to true.
4. Change the Align property to alClient. The Image component expands to fill the
client area of the form.
5. Choose File | Save and save the form’s unit as MDIChild.
6. Switch to the Code Editor (press F12). Click on the ViewMain.cpp tab. Now choose
File | Include Unit Hdr from the main menu, select the MDIChild unit, and click
OK. This is so the compiler is happy when we reference the TChild object.
The form is pretty unimpressive at this point, but it should look similar to Figure 6.17.
Figure 6.17.
The MDI child form
with an Image
component.
We still have to create the About box, but right now you’re probably eager to try the program.
Go ahead and click the Run button. After a while, the program is displayed. You can choose
File | Open and open any graphics file (any file with a .bmp, a .wmf, or an .ico extension, that
is). Notice that the MDI child window sizes itself to the graphic it contains. Open several files
and then try the Cascade and Tile options under the Window menu. If you want, you can
save a file with a different name using the File | Save As menu item.
Step 5: Create the About Box
By now you should know enough about C++Builder to create the About box on your own.
Create the About box so that it looks something like Figure 6.18. If you get stuck, you can
jump back a few pages and review the steps you took to create the About box earlier in the
chapter. Feel free to make your About box as personalized as you like.
