Thank you

Hi,
Please note that you can not use the choice group,textfield etc on the lo level API..you have to use the Form for these..however you can customize the canvas and you can provide the same look and feel like choice group.

IS this the MUST requirement using that choicegroup on canvas..
Thanks,

Hi Raj,

Cause i want to allow to user to select the size of the image and on released, the animation will be able to preview on the same canvas, thus choicegroup is used, unless you have any suggestion to replace the choicegroup?

Hi,
You mean to say is that you will first take the input for the size of the image....correct..

Yes off course this can be done without the choicegroup...you can simpley draw the menu like screen then let the user select out of the same,have the selection of the size..in a int var..then draw the images..
for any more query you can write again..
Thanks,

Hi raj,

currently our problem is that:
we have this canvas with a Form
including choicegroup and stuffs.

we wanted to put an Sprite threading image ON TOP of the form

is this possible?

afaik u cannot "add" a choiceGroup on a Canvas, nor a Form...
They are both Displayables and you can only show one Displayable at a time...
I think raj_j2me is trying to say that u might want to implement ur own choicegroup on the Canvas ; as in draw it urself
As u know u can draw on the canvas so u might actually draw ur own Choicegroup... it's quite some work especially implementing the logic for animation regarding selection of one of the items of a ChoiceGroup...

U might want to use a normal form with a choicegroup, and when one is selected the Canvas will pop up (replacing the Form with choicegroup) and there u can draw the Sprites u want to draw...

Well,

Let me jump in...

You cannot use High Level UI within Low Level UI.
But you can do it in the other side using a CustomItem within a Form.

CustomItem allows you to use some canvas functionallity, detect keystrokes, paint and there is also a means to traverse it and set a prefferred size.

Check it carefully, there are lots of things you can do with it.
