handling system objects

allowed instead of the following command:

Code:

---

Lianja.get("page.section").filter = m.my_filter

---

to write this?

Code:

---

my_sec = Lianja.get("page.section")
my_sec.filter = m.my_filter

---

and can I use it this way?

Code:

---

my_grid = Lianja.get("page.section").Grid
my_row = my_grid.activerow

---

Hi Sandor,

Yes.

You can try in the command window with an app open.

Attachment 2751

and what happens in this case?

Code:

---

my_row = fx_row()

procedure fx_row
my_grid = Lianja.get("page.section").grid
return my_grid.activerow

---

same:

Code:

---

my_grid = Lianja.get("page.section").grid

rele my_grid
? Lianja.get("page.section").grid      (Uundefined)

Hi Strato,

I've modified example_gridfilter to show some of these cases (lib_page1_section2.prg).
So we have a common starting point and it is reproducible for everyone.

Code:

---

////////////////////////////////////////////////////////////////
// Event delegate for 'click' event
proc page1_section2_field1_click()
    Lianja.get("section1").grid.filter = "startsWith(customerid, 'B')"
   
    my_grid=Lianja.get("section1").grid
    messagebox(vartype(my_grid))
endproc


////////////////////////////////////////////////////////////////
// Event delegate for 'click' event
proc page1_section2_field2_click()
    my_row=Lianja.get("section1").grid.activerow
    messagebox(transform(my_row,''))


    Lianja.get("section1").grid.filter = "startsWith(customerid, 'A')"
endproc

////////////////////////////////////////////////////////////////
// Event delegate for 'click' event
proc page1_section2_field3_click()
    //Lianja.get("section1").grid.filter = ""


    my_grid=Lianja.get("section1").grid
    my_grid.filter=""
endproc

These are buttons B and A.

Results:
Button A clicked: some number (of selected row before filtering in this example)
Button B clicked: O (=object type)
Button C clicked: no filter value

Parsing the commands is tricky in a programming language, so I use variables here, not the whole expressions.

hi Josip,
did you try to click multiple times to buttons?

I did. Nothing unexpected.
Did you try to put this code into this example in your Lianja installation?

There is an issue in the beta you downloaded. It has been fixed in 7.0RC2.
