FIX: Can't Move Focus from a Toolbar to an Object on a Form

The information in this article applies to:

• Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b

SYMPTOMS

Attempts to use SetFocus to move the focus from an object in a toolbar to an object on a form within a formset does not work. The focus never leaves the previously active control, which is another object on the form. This problem occurs only with formsets.

WORKAROUND

Step-by-Step Workaround

Create an instance of the toolbar as a separate object and the form as a separate object. Then the code _SCREEN.ActiveForm.Text1.SetFocus in the command button on the toolbar works just fine. For example:

1. Use this command:

   MODIFY FORM Myformset

2. Select the ToolBar1 form.

3. On the Form menu, click Remove Form.

4. Press CTRL+W to save your work and exit from the Form Designer.

5. Use this command:

   MODIFY CLASS mytoolbar OF mytestlib

6. Double-click the command button on the Toolbar.

7. Replace this code:

         THISFORMSET.FORM1.Text1.SetFocus
   

   with this code:

         _SCREEN.ActiveForm.Text1.SetFocus
   

8. Press CTRL+W to save your work and exit from the Class Designer.

9. Type the following commands in the Command window:

   SET CLASSLIB TO mytestlib.vcx oToolBar = CREATEOBJECT("mytoolbar") oToolBar.SHOW DO FORM myformset.

10. Click the second text box object (the one below) on Form1.

11. Click the New button on the toolbar.

Alternative Step-by-Step Workaround

Another workaround if you must use a formset is to place a timer object on the form that uses SetFocus to move the focus to Text1 on the form. For example:

1. Use the following command:

   MODIFY CLASS mytoolbar OF mytestlib.

2. Double-click the command button on the toolbar.

3. Replace this code:

         THISFORMSET.FORM1.Text1.SetFocus
   

   with this code:

         THISFORMSET.FORM1.Timer1.Enabled = .T.
   

4. Add a timer object to Form1.

5. Set the timer's Interval property to 10.

6. In the timer's Timer event, add this code:

   THISFORMSET.FORM1.Text1.SetFocus THIS.Enabled=.F.

7. Press CTRL+W to save the formset and exit from the Form Designer.

8. Use this command:

   DO FORM myformset

9. Click the second Text Box object (the one below) on Form1.

10. Click the New button on the toolbar.

STATUS
