Child Dialog (Sub Forms)
By Daniel Zuppinger
A simple class for handling Child Dialogs within a dialog or property sheet. These Child Dialogs can be changed on the fly, much like subforms. It's a simple task really, but I got tired of programming everything everytime :-(
Step 1. Design one or several 'Subdialogs'. Make sure to set the Style to 'Child' and to tick the property 'Control'.
Step 2. Design a Parent Dialog. To make things easier I add a static control for easier positioning of the child dialogs (normally I use a group frame).
Step 3. Generate for all dialogs their classes.
Step 4. Add the files 'SubFormCollection.cpp' and 'SubFormCollection.h' to your project.
Step 5. Create an object of the class CSubFormCollection to the parent dialog.
Step 6. In the OnInitDialog() method of the parent class add the code below :
(GetDlgItem(IDC_SUBFORM_FRAME))->GetWindowRect(&r); // get the position for the subforms
// m_SubForms.SetRelPos(r); // if the positioning is absolute use this, else the next line
m_SubForms.SetCenterPos(r); // centers the subdialog within the static IDC_SUBFORM_FRAME
m_SubForms.CreateSubForm(IDD_SUBFORM1,this); // create the sub forms
m_SubForms.ShowSubForm(); // show the first one
Step 7. To switch between the subdialogs use the code below :
Now the big work starts...
