Combobox lostfocus problem - is this a bug?

Hi

Please consider this sample.


	Code: #include <hmg.ch> Function Main define window sample at 0, 0 width 300 height 300 main define combobox one row 10 col 10 width 100 on lostfocus do_one() end combobox define textbox two row 40 col 10 width 100 on lostfocus do_two() end textbox end window sample.one.additem( 'One' ) sample.one.additem( 'Two' ) sample.center() sample.activate() Return function do_one if sample.one.value == 0 sample.one.setfocus() endif return nil function do_two if len( alltrim( sample.two.value ) ) == 0 sample.two.setfocus() endif return nil

While running, just press <tab> and the focus will move to the second control. But, I think it should be in the first control itself. Is this a bug?

Hi Mr. Rathinagiri,

It is not a bug. You have commited a little mistake in your function do_two replace this line: sample.two.setfocus() by this sample.one.setfocus(). It was backing at same place, after two would pass to combobox one.

Hi Rathi,

No, it isn't. You should correct your function do_two as showed in the updated sample below:


	Code: #include <hmg.ch> Function Main define window sample at 0, 0 width 300 height 300 main define combobox one row 10 col 10 width 100 on lostfocus do_one() end combobox define textbox two row 40 col 10 width 100 on lostfocus do_two() end textbox end window sample.one.additem( 'One' ) sample.one.additem( 'Two' ) sample.center() sample.activate() Return function do_one if sample.one.value == 0 sample.one.setfocus() endif return nil function do_two if len( alltrim( sample.two.value ) ) == 0 .and. sample.one.value != 0 sample.two.setfocus() endif return nil

Hope that helps :idea:

Control 'one' lostfocus is fired after control 'two' gotfocus.

Am I correct?
