grid reload event

[meerkat]

When a grid is reloaded it executes the selection event for the first row.
Is this a feature?

Is this a feature?

If this is a feature, is there a way to turn it off.
When a grid is reloaded it executes the trigger for the selection of item 0 in the grid.
Currently I fill grid items 1 -> n. If I get a selection of item 0 I ignore it.

Thanks for the help..

G'Day Dan, not sure I understand the problem exactly, What I see when the grid is loaded  is the location (highlighted and prints to mainwin) ie cellxy$() which is 0,0

and not the contents of the cell ie the value$().

can you throw up some code for us to see the problem

Howdy, yAll down yunder..
The program I have is rather large and complex with 5 grids.
What I want is:
Selection of a item in grid 1 will reload grid 2
Selection of a item in grid 2 will reload grid 3 .....>>

However;
A simple example. We have a country with states, states with county, and county with cities.
dim countryGrid$(1,10)
dim stateGrid$(1,10)
dim countyGrid$(1,10)
dim cityGrid(1,10)
grid #main.gCountry, countryGrid$(), [useCountry] ,col,row,wide,high
grid #main.gstate, stateGrid$(), [useState] ,col,row,wide,high
grid #main.gCounty, countyGrid$(), [useCounty] ,col,row,wide,high
grid #main.gCity, cityGrid$(), [useCity] ,col,row,wide,high


' To get started, fill the countryGrid$() with desired countries. Then reload() it.
' The reload of #main.gCountry causes it to go to the lable [useCountry]
' as if the first line (0) was selected (clicked).

#main.gCountry reload()
wait

' This label is executed with col$,row$ at zero. No one has selected (clicked)
' anything in the country grid. It is executed after the reload() command,
' when I think it should have waited (wait).
'
[useCountry]
xy$ = #main.gCountry cellxy$()
col$ = word$(xy$,1," ") ' this is zero
row$ = word$(xy$,2," ") ' this is zero

Thanks for the help..

yAll have a great day.

Hav'n a great day here Dan, glass half full (and it's red)

If I understand this correctly I think it's a bug , I simply set the selectxy() outside the range after a reload to avoid the issue

not really done any testing though (and code just thrown together)

EDIT: using reload() before the wait statement causes an automatic selection of grid(0,0)

dim countryGrid$(1,10)
dim stateGrid$(1,10)
dim cityGrid$(1,10)
countryGrid$(0,0)="USA"
countryGrid$(0,1)="UK"
countryGrid$(0,2)="RUSSIA"
countryGrid$(0,3)="CHINA"
countryGrid$(0,4)="AUSTRALIA"
stateGrid$(0,0) = "WA"
cityGrid$(0,0)= "PERTH"
col=20:row=40:wide=200:high=90

WindowWidth=900
WindowHeight=650
textbox #main.tb1,300,200,100,30
grid #main.gCountry, countryGrid$(), [useCountry] ,col+20,row+10,wide,high
grid #main.gstate, stateGrid$(), [useState] ,col+20,row+100,wide,high
grid #main.gCity, cityGrid$(), [useCity] ,col+20,row+200,wide,high
open "Grid test" for window as #main
#main.gCountry columnwidths(100)
' To get started, fill the countryGrid$() with desired countries. Then reload() it.
' The reload of #main.gCountry causes it to go to the lable [useCountry]
' as if the first line (0) was selected (clicked).

'#main.gCountry selectxy(100,100)
#main.gCountry reload() '**************CAUSES GRID TO MAKE CHOICE **********
wait
' This label is executed with col$,row$ at zero. No one has selected (clicked)
' anything in the country grid. It is executed after the reload() command,
' when I think it should have waited (wait).
'
[useCountry]
xy$ = #main.gCountry cellxy$()
#main.tb1 xy$
print xy$
print "clicked: "; #main.gCountry cellxy$()

'#main.gCountry reload()
'#main.gCountry selectxy(100,100)'**********REMOVES FOCUS AFTER A SELECTION
WAIT
[useState]

xy$ = #main.gstate cellxy$()
print "clicked: "; #main.gstate cellxy$()
#main.gstate reload()
#main.gstate selectxy(100,100)
WAIT
[useCity]

Are you referring to the drawing behavior of stacking the grids on top of each other?

Sorry Carl just thrown together before I hit the sack down here.
The first position in a grid is automatically selected upon a reload of a grid
So if Dan's intention is to select from a second grid based upon the fist grids selection
He will always get location 0 0 of a reloaded grid.
Hope that makes sense.

Wow! This took a couple hours to figure out. Kinda crazy to explain.

I have a grid. When I do a grid reload() it executes the grid branch label. But only if you have rownames() defined.

In the following code if you comment out #main.gDb rownames("File","Loc","Id") it works.
But if you leave the rownames() in when you run the program it executes the grid branch label [useDb]. Now comment it out again and it still executes the branch label. It seem to remember info from the previous rownames() command.

dim dbGrid$(2,10)

WindowWidth   = 1200
WindowHeight  = 570
UpperLeftX    = 200
UpperLeftY    = 200
grid          #main.gDb,      dbGrid$(),      [useDb]                   ,010,110,320,224

open "Test" for window_nf as #main
#main "Font Arial 10 Bold"

'---- grid db
#main.gDb columnwidths(120,300,50)
#main.gDb rownames("File","Loc","Id") '<<<<< Comment out to work
#main.gDb rowlabelwidth(0)
gosub [getDbInfo] ' get initial database information
wait

[exit]
close #main
end

' ----------------------------
' get grid info
' ----------------------------
[getDbInfo]
dbGrid$(0,0) = "aaa.db"
dbGrid$(1,0) = "E\LB5\"
dbGrid$(2,0) = "5"
dbGrid$(0,1) = "stockMarket.db"
dbGrid$(1,1) = "E\LB5\"
dbGrid$(2,1) = "4"
dbGrid$(0,2) = "test.db"
dbGrid$(1,2) = "E\LB5\"
dbGrid$(2,2) = "1"
dbGrid$(0,3) = "bbb.db"
dbGrid$(1,3) = "E\rbp101\projects\wine_project\data\"
dbGrid$(2,3) = "2"
dbGrid$(0,4) = "xxx.db"
dbGrid$(1,4) = "E\rbp101\projects\wineWatch_project\data\"
dbGrid$(2,4) = "3"
#main.gDb  reload()
print "Just completed reload"
RETURN

' ----------------------------------
' Selected dbFile
' create grid for this DB
' ----------------------------------
[useDb]
xy$ = #main.gDb cellxy$()
col$ = word$(xy$,1," ")
row$ = word$(xy$,2," ")
col = val(col$)
row = val(row$)
print "why am i here"
wait

RETURN


Hope this helps..
