Hello All,
Is it feasable for the new version of LWUIT that developer is able to have the capabilites to add checkboxes to a group like the radiobutton bcz we faced a lot of cases when we have a multiple selection in a group of dynamich choices where we could not create for each choice a checkbox object as per the radiobutton a simple for loop with one radiobutton object and a group can be dynamically created.
thank you
Elie

Hi,
Save your dynamic choices in an array or a vector.

Thank you Chen for your reply,
the point that i am talking about is when creating the object and adding it to the form espacially with reference to dynamic issue below is a description of what i meant:
a cehckbox case:
for each choice we should create its own object evaluate for a choice of 200 checkbox  :
CheckBox firstCB = new CheckBox("First CheckBox");
firstCB.getStyle().setMargin(Component.TOP, 1);
f.addComponent(firstCB);
firstCB.getStyle().setMargin(Component.BOTTOM, 0);
CheckBox secondCB = new CheckBox("Second CheckBox");
secondCB.getStyle().setMargin(0, 5, 2, 2);
f.addComponent(secondCB);
and we should chsk each object alone to get selection otherwise in the case of a radiobutton we create a for loop of 200 count and create one radobutton object and one group ( the group is very important to check selection this is teh main differance with the chackbox)

Hi,
If your use case is to show 200 checkbox you should use List object,
adding 200 components to a Container can be expensive.
What you should do is use List and write a renderer that returns
CheckBox in the getListCellRendererComponent method.

Chen
