No. Sorry. The container 'Canvas' is a Group containing
* a writing plane
* a hbar
* a vbar
Without the Input widget I have 3 children; with the Input widget
I have 4 children. 'children() - 2' means before the scrollbars.
The code in 'Canvas::show()':
if(inputWidget == NULL)
{
inputWidget = new Input(xx, yy - textsize_, ww, textsize_);
inputWidget->value("Hello");
inputWidget->tooltip("inputWidget");
}
// add(inputWidget);
// inputWidget->redraw();
// inputWidget->show();
insert(*inputWidget,children() - 2);
// inputWidget->redraw();
inputWidget->show();
You can see that I have tried your proposal.
The HTML page is simple:
<html><head><title>INPUT example</title></head>
<body>
BEFORE <input type="text" size="30" value="Hello you" maxlength="150"> AFTER
</body></html>
There is free space for the Input between BEFORE and AFTER. But
the widget does not exist on the writing plane: the tooltip is
not visible.
