Navigation dubts

[Davide]

Hello,

I'm starting my first IWCGJQuery Mobile Suite application and I have some dubts about navigation.

Using the following code (from your JQMWizard demo) on my main form :
1) is every new created frame stacked ?
2) I can't use the RelType-jqmrtBack function on the new created frame to go back to MainForm.
Is it available on frame created using the CreateNewFrame ?
How to go back to main form ?
3) In a two frame list view -> detail view "model" after updating the detail I need to refresh the list view.
Is better to avoid working with frame or is there a way to get a reference to the list view frame to call a "refresh" procedure on it ?
4) How to free a created frame ?

Code: Select all

function TMainForm.CreateNewFrame(AFrameClass: TIWCGFrameClass): TFrame;
var
   NewName: string;
   LControl: TIWCGJQMRegion;
begin
   NewName:= CGFindUniqueComponentName(Self, 'Frame');
   FActiveFrame:= AFrameClass.Create(Self);
   ActiveFrame.Name:= NewName;
   ActiveFrame.Parent:= Self;
   ActiveFrame.Align:= alClient;
   ActiveFrame.TabOrder:= 1;

   LControl:= FindIWFrameRegion(ActiveFrame);
   if Assigned(LControl) then
    LControl.AjaxReRender;

   Result:= ActiveFrame;
end;


About a non Ajax application navigation :
1) Is the RelType-jqmrtBack on button available ?
2) Are the forms stacked and continue to exist if I don't free them explicitely ?
Can I assume to navigate like on a desktop application ? (with create and release)

Thank you,
Davide

Hi Davide,

1) is every new created frame stacked ?

What do you mean?

2) I can't use the RelType-jqmrtBack function on the new created frame to go back to MainForm.
Is it available on frame created using the CreateNewFrame ?
How to go back to main form ?

You can use ChangePageTo method.

3) In a two frame list view -> detail view "model" after updating the detail I need to refresh the list view.
Is better to avoid working with frame or is there a way to get a reference to the list view frame to call a "refresh" procedure on it ?

delphi code

List.AjaxReRender;

4) How to free a created frame ?

Standard procedure.

About a non Ajax application navigation :
1) Is the RelType-jqmrtBack on button available ?

No, works only with ajax navigation.

2) Are the forms stacked and continue to exist if I don't free them explicitely ?
Can I assume to navigate like on a desktop application ? (with create and release)

Yes, you can

Best Regards.

Sorry but I have some dubts more...

Is it possible to specify a transition using ChangePageTo ?
What is the second parameter of ChangePageTo ?
After calling ChangePageTo the Active form is released or it continue to exists ?

Using the following code:

Code: Select all

   Frm := TAjaxPageFrame.Create(WebApplication);
   ShowAjaxButton.JQMLinkingOptions.LinkToControl := Frm.IWFrameRegion;
   Frm.IWFrameRegion.TabOrder := 1;


I can navigate from the main frame to a frame (for sample named AjaxFrame) that I create in the OnCreate event.
After press a "jqmrtBack" on the "AjaxFrame" I came back to the main frame.
I think "AjaxFrame" (the second frame) continue to exists but it isn't visible.
What about changing the data displayed by "AjaxFrame" on subsequent calls based on parameters ?
I coudn't use OnCreate cause it still exists after its first creation.
Is there an event like "OnShow" or similar that permit me to do some initialization when I show the AjaxFrame for subsequent call ?

I read about JQuery mobile form management but I don't know how it is implemented by IWCGJQuery Mobile suite.

Thank you,
Davide

Hi Davide,

Sorry for delay,

Is it possible to specify a transition using ChangePageTo ?

Yes, it is.

What is the second parameter of ChangePageTo ?

Change page options: http://api.jquerymobile.com/1.3/jQuery.mobile.changePage/

After calling ChangePageTo the Active form is released or it continue to exists ?

You should release it by yourself.

Best Regards.
