accelerator keys and the tab control

pgtips · July 10th, 2003, 09:43 AM

I have a problem with providing accelerator keys for buttons on a tab control.

Keeping it simple to save me typing, if I have a tab control with, say, 3 tabs and each tab has an Update button on it, how can I make it so that the user can hit <alt>U and that will fire the click event of the Update button on the tab that has focus. Needless to say each of the buttons has to have the caption [u]U</u>pdate.

Anyone got any neat tricks for this? Would be much appreciated.

You could change the caption of the appropriate button when the tab is selected from "Update" to "&Update", and change all the other button caption's to "Update"

For example, if you have all 3 buttons in a control array cmdUpdate (cmdUpdate(0), cmdUpdate(1) etc.), you could do something like this:

Code:

cmbUpdate(0).Caption = "Update"
cmbUpdate(1).Caption = "Update"
cmbUpdate(2).Caption = "Update"

cmdUpdate(TabSelected).Caption = "&Update"

I hope that helps.

You could always put that into a loop if you have more buttons:

Code:

For lngCount = cmdUpdate.LBound To cmdUpdate.UBound
   cmdUpdate(lngCount).Caption = "Update"
Next

cmdUpdate(TabSelected).Caption = "&Update"

There may be more efficient ways of doing this though.

Two cents.
In my opinion the Update button should be outside the tab, just like
the OK, Apply and Cancel buttons (in fact I will call it just Apply).
This is one of the GUI guidelines that I follow, but it is personal.
