Trouble adding components dynamically
Morning,
I have a situation where I am cycling through an array and for each
element in the array I need to add a set of components to a BoxPane. To
do this, I wrote a wtkx file that contained the components that I need
to create each time I go through the array. As I go through an
iteration I read in the wtkx file with a WTKXSerializer.readObject,
casting into another BoxPane, then attempt to add the new object to my
parent. Essentially like so:
WTKXSerializer wtkx = new WTKXSerializer();
BoxPane child = (BoxPane) wtxk.readObject(this,"myfile.wtkx");
parent.add(child);
This as I go through my application I get no errors, no warnings, but
myfile.wtkx does not actually display. I tried doing something akin to
child.setVisible(true), but it hasn't made any difference.
I thought that maybe there was an issue with my parent BoxPane, so I
tried including myfile.wtkx as a wtkx:include parameter in the parent
file, and to my surprise the components in myfile.wtkx displayed as I
would have expected it to using the programmatic method. Am I doing
something clearly wrong? Is there likely an issue with my parent or
child wtkx file that I should be looking for?
Also, the parent.add(child) is executing...its not like I never get to
that block of code...feel like I need to mention that since it's the
first thing that comes to mind as a simple issue.
Thanks for any thoughts.
David

I can certainly understand your frustration. We've all been there. :-)
You may want to look into using the Bindable interface. It is designed to help simplify the task of loading and binding to multiple WTKX files and includes. It is new and not well-documented at the moment, but you can see an example here:
http://svn.apache.org/repos/asf/pivot/trunk/tests/src/org/apache/pivot/tests/BindableTest.java
http://svn.apache.org/repos/asf/pivot/trunk/tests/src/org/apache/pivot/tests/BindableWindow.java
http://svn.apache.org/repos/asf/pivot/trunk/tests/src/org/apache/pivot/tests/BindableWindow.json
http://svn.apache.org/repos/asf/pivot/trunk/tests/src/org/apache/pivot/tests/bindable_test.wtkx
Basically, the idea is that you create a custom subclass of your root element class that implements Bindable. Then WTKXSerializer calls the initialize() method to notify you when all of the variables have been bound.

Posted by David McNelis <Dm...@sharedmarketing.com>.
I figured out what my issue was, and it has to do, I think, with Greg's
earlier email about what I'm trying to add to.
Because I initially lacked a bit of understanding about the
pre-processing of the wtkx:include directive I had set up multiple
WTKXSerializers for each of my different markup files in order to bind
what I needed to be able to edit. So, my "parent" was being set up by
serializer B, while the "grandparent" was in serializer A. When I just
changed the parent to be built based off of serializer A, everything
started showing up.
Thank you all, for your patience in helping me with this problem. I
don't know if I should laugh at the simplicity of the solution, or cry
for the day and a half I've been pounding my head on my desk for this
because I'm an idiot.
Again, thanks.

Hi David,
I tried reproducing your example given your code, and the child.wtkx
file shows up for me when added programatically. One thing was a little
weird though -- the fact that you have the preferred size of the parent
border set to the same as the preferred size of the child box pane means
that each child box pane will take up the size of the border entirely.
Couple this with the fact that you're using a verticalScrollBarPolicy of
"fill" means that you're guaranteed to never see any but the first box
pane. If I let the scroll pane keep its default vertical scroll bar
policy ("auto"), then a scroll bar shows up, and I see the child box
panes...

Are you adding the parent to the tab pane's tab sequence, or directly to
the tab pane itself? If you are doing the latter, it could definitely be

That sounds like it should work. Can you provide some sample code? That

Yeah, your understanding is correct.

RE: Trouble adding components dynamically
Posted by David McNelis <Dm...@sharedmarketing.com>.
I'm including the "parent" inside the tab in the 'grandparent' wtkx
file, which is structured thusly:
<?xml version="1.0" encoding="UTF-8"?>
<Window title="Template Builder UI!" maximized="true"
xmlns:wtkx="http://pivot.apache.org/wtkx" xmlns="org.apache.pivot.wtk">
<content>
<Border styles="{padding:12}">
<content>
<BoxPane>
<TabPane>
<tabs>
<BoxPane TabPane.label="tab number 1"
styles="{horizontalAlignment:'center', verticalAlignment:'center'}"
wtkx:id="tab1">
<!--
content -->
</BoxPane>
<BoxPane wtkx:id="tab2"
TabPane.label="tab number 2"
styles="{horizontalAlignment:'center', verticalAlignment:'center'}">
<wtkx:include
src="parent.xml">
</wtkx:include>
</BoxPane>
</tabs></TabPane></BoxPane></content></Border></content></Window>
My understanding is that the parent.xml would be compiled into the
'grandparent' file and would end up in the tab panes sequence. Do I
understand that correctly?

Are you adding the parent to the tab pane's tab sequence, or directly to
the tab pane itself? If you are doing the latter, it could definitely be
the cause of the problem.

That sounds like it should work. Can you provide some sample code? That

RE: Trouble adding components dynamically
Posted by David McNelis <Dm...@sharedmarketing.com>.
I also tried adding a test label to my parent wtkx, then loading it into
the code, with
Label testLabel = (Label) parentSerializer.get("testLabel");
I then spit out the current label text. Then set the label to different
text. However the new text value never ends up being re-painted on the
screen, despite direct calls to repaint the label, the box pane, the
window... but when I spit the testLabel.getText() to system out again,
it does contain the new value.
I don't know if it makes any difference but the parent component hear is
living inside a TabPane...I had left that out previously because it
seems kind of inconsequential...and in my other TabPanes I haven't had
issues adding or removing components.

Hopefully this doesn't get too jacked up in email, but here is an
excerpt of the code and the wtkx files that I'm using. I also tried
just adding a test label to the containerPane as well and that did not
show up either. But if I wtkx:include the child component as a child of
the "containerPane" then the child component does display.
Code:
containerPane = (BoxPane)parentSerializer.get("containerPane");
for(int i=0, n=array.getLength(); i<n; i++){
WTKXSerializer wtkx = new WTKXSerializer();
BoxPane singlePane = null;
try {
singlePane =
(BoxPane)wtkx.readObject(this, "child.wtkx");
} catch (IOException e) {
e.printStackTrace();
} catch (SerializationException e) {
e.printStackTrace();
}
singlePane.setVisible(true);
containerPane.add(singlePane);
}

That sounds like it should work. Can you provide some sample code? That
might help identify the issue.

Thanks for any thoughts.
