:SetFocus problem with WHEN clause in Gets and Pushbuttons

[RAMESHBABU]

I have a problem with :SetFocus()

In the following code I have three gets and three pushbuttons.

By default the Gets are disabled and when the "Create" button
is pressed, the gets should be enabled and the focus should be
placed on the 1st get. The "Create" and "Save" functions of my
code below is working Ok enabling and disabling the gets.

But the oGet1:SetFocus() in Create() function and oBtn1:SetFocus()
in Save() function are not working at all.

I tried with oDlg:Update() and oDlg:Refresh() also in both Create()
and Save() functions without sucess.

Can anybody look into the code and suggest me where I am going
wrong?

I am using FWH 2.8 (September Build) + xHarbour 0.99.61 (Simplex)

Thanks

Ramesh,

Try this:

oGet1:PostMsg( WM_SETFOCUS ) instead of oGet1:SetFocus()

Mr.Antonio

Amazing to get a solution in 5 minues time.

It is working now Ok.

Thank you very much.

BTW, why :SetFocus() is not working!

Hi Mr.Antonio

Once the focus is passed on to a get with oGet1:PostMsg(EM_SETFOCUS)
and when I click on any other controls or press tab, the blinking cursor is
still showing on old control (oGet1) and bLostFocus is also not working
properly.

Just add the following lines to the above code after redefinition of GETS,
implement the oGet1:SetFocus(WM_SETFOCUS) in place of
oGet1:SetFocus(), oBtn1:SetFocus(WM_SETFOCUS) in place of
oBtn1:SetFocus() and test it. You will find the anomaly.

Code: Select all  Expand view

oGet1:bGotFocus  := {||oGet1:SetColor(nRGB(0,0,0), nRGB(193,193,255))}
oGet1:bLostFocus := {||oGet1:SetColor(nRGB(0,0,0), nRGB(255,255,255))}


Thanks to you

Ramesh,

Try this:

oGet1:PostMsg( WM_SETFOCUS )
oBtn1:oJump = oGet1

[Antonio Linares]

Ramesh,

> BTW, why :SetFocus() is not working

Because Windows returns the focus to the button, after processing the ACTION of the button, so we can not interrupt that process.

[RAMESHBABU]

Hello Mr.Antonio

Thanks again for immediate attention.

oBtn1:oJump = oGet1

If we do not know in advance that the user will jump to oGet1 from oBtn1?

Thanks

Ramesh,

> If we do not know in advance that the user will jump to oGet1 from oBtn1?

You set it from the Create() function where you know where it will go.

Mr.Antonio

Kindly test the above code with the changes you have suggested
and give me the suitable solution please.

I tried with the all your suggestions with fail.

Ramesh,

Code: Select all  Expand view

FUNCTION Create(lCreate, lSave, lGo, oGet1 )

lSave   := .T.
lCreate := .F.
lGo     := .T.

oGet1:PostMsg( WM_LBUTTONDOWN )
oGet1:PostMsg( WM_LBUTTONUP )

RETURN nil


[RAMESHBABU]

Mr.Antonio

Thank you very much for your reply.

After spending some time on this, I could get the
required effect with the following statement.

oGet1:PostMsg( WM_RBUTTONDOWN )
