With my GeoExt code, it looks like that (there is also something for the
font size):
var labelForm = new Ext.form.FormPanel({
items:[{
xtype: "textarea",
name: "label",
value: "",
fieldLabel: "Text "
},{
xtype: "combo",
store: [10,12,14,16,18,20,22,24,26,28,30],
displayField: "fontsize",
fieldLabel: "Font size ",
typeAhead: true,
mode: "local",
triggerAction: "all",
editable: false,
}],
buttons: [{
text: "Validate",
handler: function() {
var labelValue = labelForm.items.items[0].getValue(); //get the typed
text
var fontSize = labelForm.items.items[1].getValue(); /:get the
selected font size
e.feature.style = {label: labelValue, labelSelect: true, fontSize:
fontSize}; //labelSelect allows to drag the text
labelWindow.close(); //The labelForm is
shown in an Ext.Window
drawLayer.redraw(); //Refresh needed to
apply the label
}
}]
});
This code is inserted in a drawFeature control, on "featureAdded". The
drag property works if you have and activate an OpenLayers control
allowing to drag a feature on the same layer (like a dragFeature or
modifyFeature control). In this case, you can select directly the text
without displaying any point.
If you adapt the code for OpenLayers, it should work without GeoExt.

Any chance you could share your code / show an example? would be
interested to see the dragging functionality.
THanks,

Thanks! That's just what I have done! It works great! But I didn't use
the
attributes property: I don't need to save the label text in a database.
I
store the written text directly inside the 'label' property. It's also
useful to add a 'labelSelect' property with 'true' to drag the text once
written. It could be interesting to create an OpenLayers example about
this.
It is a very simple tip, but quite useful.
PS: it works also with GeoExt and a FormPanel to write the text.

Try adding a drawfeature control, that prompts for a text and sets it
as
the
label. Should be something like this this:
var control = new OpenLayers.Control.DrawFeature(
layer,
OpenLayers.Handler.Point, {
featureAdded: function(feature) {
feature.attributes.text = prompt('Write here:', '');
feature.style.label = feature.attributes.text;
feature.layer.drawFeature(feature);
}
}
);
