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.

Subject: RE: Trouble adding components dynamically
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);
}
Parent component:
<Border xmlns:wtkx="http://pivot.apache.org/wtkx";
xmlns="org.apache.pivot.wtk" preferredWidth="800" preferredHeight="600">
<content>
<ScrollPane horizontalScrollBarPolicy="fill"
verticalScrollBarPolicy="fill">
<view>
<BoxPane orientation="vertical"
wtkx:id="containerPane">
</BoxPane>
</view></ScrollPane></content></Border>
Child component:
<BoxPane xmlns:wtkx="http://pivot.apache.org/wtkx";
xmlns="org.apache.pivot.wtk" preferredWidth="800" preferredHeight="600"
orientation="vertical">
<BoxPane orientation="vertical" wtkx:id="childPane">
<BoxPane orientation="horizontal">
<Label text="Blah blah"></Label>
<ListButton
wtkx:id="button1"></ListButton>
<Label text="Blah blah:"></Label>
<ListButton
wtkx:id="button2"></ListButton>
</BoxPane>
<BoxPane orientation="vertical">
<Label text="Filler:"></Label>
<Border>
<content>
<ScrollPane preferredHeight="25"
horizontalScrollBarPolicy="fill"
verticalScrollBarPolicy="fill_to_capacity">
<view>
<TextArea wtkx:id="textarea1"
preferredWidth="600" text="Sample Text">
</TextArea>
</view>
</ScrollPane>
</content>
</Border>
</BoxPane>
<BoxPane orientation="vertical">
<Label text="More stuff:"></Label>
<Border>
<content>
<ScrollPane preferredHeight="100"
horizontalScrollBarPolicy="fill"
verticalScrollBarPolicy="fill_to_capacity">

<TextArea wtkx:id="textarea2"

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

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
