@ 3,2 DCBROWSE oVBrowse; //PARENT oTabPage1 ;

DCBROWSECOL FIELD &felder1 WIDTH 10 ;

You would have to use the navigation methods of the XbpBrowse() class.
Code: Select all
@ .. dcpushbutton caption 'Up' action {||oBrowse:up(),oBrowse:forceStable()}
@ .. dcpushbutton caption 'Down' action {||oBrowse:down(),oBrowse:forceStable()}
@ .. dcpushbutton caption 'Left' action {||oBrowse:left(),oBrowse:forceStable()}
@ .. dcpushbutton caption 'Right' action {||oBrowse:right(),oBrowse:forceStable()}

thank you, Roger
for your quick an fitting advice. I combine it with your earlier advice:
DCHOTKEY xbeK_UP ACTION .....
and so I can offer to the user the complete navigation system used by keys or mouse.

Hi Roger,
for this problem you gave me a good advice. But I used DCHOTKEY xbeK_UP ACTION {||oBrowse:down(),oBrowse:forceStable()}
instead of dcpushbutton caption 'Down' action {||oBrowse:down(),oBrowse:forceStable()} which works really good,
but since I use DCBROWSE .... EDIT xbeBRW_ItemSelected for editing a cell by doubleclick, which works right too,
I have the problem, that using a navigation key
after having edited a cell by doubleclick, the cursor jumps two cells instead of one, definitively triggered by the DCHOTKEY xbeK_up etc.
which ist not really pleasant.
Is there a chance to avoid this?
Code: Select all
calias1=alias()
@ 3,2 DCBROWSE oBrowse DATA calias1 SIZE wcol,wrow FONT textfont ;
[b]EDIT xbeBRW_ItemSelected[/b] MODE DCGUI_BROWSE_EDITEXIT ;

I don't know why this would be happening.
I will need to write a test program to figure it out.
You could help me out by writing one for me.
I'm a bit busy today.

Roger,
I modified your FUNCTION XSample_10 in XDEMO and added the DCHOTKEY lines enabling the navigation in the table without first clicking in.
I disabled the HOTKEY xbeK_UP to show you the difference between navigation up and down . I added the database collect.dbf and collect.ntx
for other users who want to simulate the bug.
Thank you for trying to find a solution.

hi obelix
- the data file (DBF File) contains a memo field and the DBT File is absent, copy the DBT file to test directory.
- Try to ignore the control the HOTKEY
.
.
/*
//DCHOTKEY xbeK_UP ACTION {||oBrowse:up(),oBrowse:forceStable()} //65574
DCHOTKEY xbeK_DOWN ACTION {||oBrowse:down(),oBrowse:forceStable()} //65576

Thank you Messoud for your posting, I'll try your proposal soon,
I added collect.dbt to my attachement
Oh I tried it and it really works
It seems to be the solution. I just needed an impulse to my app to navigate in the browsed table.
thank you for your help.
Peter
