UniPropertyGrid / uniAddProperties

[JDDEV]

Hi all,

I would like to use a uniPropertyGrid component without a AttachedComponent : just like a TValueListEditor component.

I find the AddProperty function but i don't find an explicit help to use it.

Is it possible to work with uniPropertyGrid  like a TValueListEditor ?

Thank you

Hi,

procedure TMainForm.UniFormCreate(Sender: TObject);
begin
  UniPropertyGrid1.AttachedComponent := Nil;
  UniPropertyGrid1.AddProperty(['Prop1', 'Value1', 'Prop2', 'Value2']);
end;

procedure TMainForm.UniPropertyGrid1PropertyChange(Sender: TObject;
  const PropName: string; var PropValue: string; var Handled: Boolean);
begin
   //
end;

Thanks,

I do exactly the same code, but the result is empty

What is wrong ?

 

PS : i use version n° 1.90.0.1496

Can you make a simple testcase for this?

Hi,

this is a testcase from the demo "Property Grid".

 

Property Grid.zip

I have just modified these lines from the demo :

procedure TMainForm.UniComboBox1Change(Sender: TObject);
var
  componentName:string;
begin
  componentName := UniComboBox1.Items[UniComboBox1.ItemIndex];
  if componentName='Perso' then begin
    UniPropertyGrid1.AttachedComponent := Nil;
    UniPropertyGrid1.AddProperty(['Prop1', 'Value1', 'Prop2', 'Value2']);
  end else UniPropertyGrid1.AttachedComponent := MainForm.FindComponent(componentName);
end;

Hi,

As a workaround, you can try this approach:

type TExPGrid = class(TUniCustomPropertyGrid)

end;

...
  UniPropertyGrid1.AddProperty(['Prop1', 'Value1', 'Prop2', 'Value2']);
  TExPGrid(UniPropertyGrid1).PopulateGrid;
...

Thanks, it is working well , Is it a bug ?

Is it possible to define type of properties ? (boolean, list of items...)

boolean

UniPropertyGrid1.AddProperty(['Prop1', True]);

Thanks.

If i well understand, it is not possible to have a property with a combobox editor and a list of items to choice ?

Hi,

You can try this approach:

  UniPropertyGrid1.AddProperty(['Prop1', True]);
  UniPropertyGrid1.AddProperty(['Prop2', 'B']); //combobox
  TExPGrid(UniPropertyGrid1).PopulateGrid;
  
  UniPropertyGrid1.JSInterface.JSCode(#1'.sourceConfig = {Prop2: {editor: new Ext.grid.CellEditor({field: new Ext.form.field.ComboBox({editable: false, store:["A", "B", "C"]})})}};');

Thanks, it is working well.

And now, i would like to get a property value...i don't find the function to do that ;(

Do you have the solution ?

?

[JDDEV]

I am waiting for a get and a set function to manage values, but if it is not possible PropertyChange Event  is the solution.

Thanks.

Good to know about

... sourceConfig = {Prop2" ...

How can we add "Items" collection editor to the PropertyGrid for respective components ?
