cXtra - Xtra for Macromedia Director

There are two kinds of objects in the grid:

Buttons, checkbox
- Are always visible on the grid
ComboBox, EditFilters, DatePicker, TimePicker
- Are only visible on the grid when you enter in Edition mode by double clicking on a cell
- Editors are not saved par cell in order to use less memory so you should use the GetEditorType event to set the editor in a cell

Buttons

Buttons can be added with:

sprite(1).SetbuttonHere(2,2,true)

And deleted with:

sprite(1).SetbuttonHere(2,2,false)

You can trap the event when a user click on a button with:

on ButtonClick me, col, row
put "Button clicked on cell ("&col&","&row&")"
end

Checkbox

Checkbox can ba added with:

sprite(1).SetCheckBoxHere(2,2,true)

And deleted with:

sprite(1).SetCheckBoxHere(2,2,false)

You can set the state with:

sprite(1).SetChecked(2,2,true)

And get the state with:

put sprite(1).GetChecked(2,2)

ComboBox, EditFilters, DatePicker, TimePicker

We don't associate an editor to a cell in the xtra to preserve the memory: for example, it's useless to see the combobox in the grid until you are in Edition mode, only the selected value is important.

So you set the editor with the GetEditorType event which is called each time the user enter in the Edition mode in the grid:

on GetEditorType me, ACol, ARow

This script is a movie script, it's not a behavior on the sprite.
You can choose one value between:

Edit = 0
ComboEdit = 1
ComboList = 2
DatePicker = 3
TimePicker = 4
CheckBox = 5
EditNumber = 6 -- allow characters [0-9] + the decimal character (specified in the decimalseparator property)
EditFilter = 7 -- allow characters specified in the EditFilter property
Button = 8

And return this value to set the Editor. For example, this code place a combobox in the cell (2,2) when the user doubleclick on this cell:

on GetEditorType me, col, row
if col=2 and row=2 then
return 2 -- show ComboList on cell (2,2)
end if
end

In this example, the combobox is empty, you can fill it with:

on GetEditorType me, col, row
if col=2 and row=2 then
sprite(1).ClearCombo()
sprite(1).AddComboItem("Red","Green","Blue")
return 2 -- show ComboList on cell (2,2)
end if
end
