Small update: over the weekend I rewrote the introspection data generator
using libclang (we can't release the code we've written in the past). I'm
very positive about libclang, but there are a few small features missing in
libclang to make it complete - I'm also working on that. This introspection
step generates data structures (actually python files) that describe the Wt
API. These files are then fed into binding generator scripts, also written
in python, which generate the proper python bindings for the Wt API.
Shortly after I have some experience on how the (old) generator behaves
with the current Wt state, I plan to make it available, even with limited
support.
Below: another pywt example to give an idea about what we're aiminng at.
BR,
Wim.
import sys
import Wt
def createDragImage(url, smallurl, mimeType, p):
result = Wt.WImage(url, "", p);
dragImage = Wt.WImage(smallurl, "", p);
result.setDraggable(mimeType, dragImage, True, None);
return result;
class Character(Wt.WText):
def __init__(self, name, parent):
Wt.WText.__init__(self, "", Wt.XHTMLText, parent)
self.name = name
self.redDrops = 0
self.blueDrops = 0
self.setText(name + " got no pills")
self.setStyleClass("character");
self.acceptDrops("red-pill", "red-drop-site");
self.acceptDrops("blue-pill", "blue-drop-site");
self.setInline(False);
def dropEvent(self, event):
if event.mimeType() == "red-pill":
self.redDrops = self.redDrops +1
if event.mimeType() == "blue-pill":
self.blueDrops = self.blueDrops +1
text = self.name + " got ";
if self.redDrops != 0:
text = text + str(self.redDrops) + " red pill"
if self.redDrops > 1: text = text + "s"
if self.redDrops != 0 and self.blueDrops != 0:
text = text + " and "
if self.blueDrops != 0:
text = text + str(self.blueDrops) + " blue pill"
if self.blueDrops > 1: text = text + "s"
self.setText(text);
def createApp(env):
app = Wt.WApplication(env);
app.setTitle("Drag & drop");
Wt.WPushButton("Quit", app.root()).clicked().connect(app.quit)
Wt.WText("<h1>Wt Drag & drop example.</h1>", Wt.XHTMLText,
app.root());
Wt.WText("<p>Help these people with their decision by dragging one of
the pills.</p>", Wt.XHTMLText, app.root());
if not env.javaScript():
Wt.WText("<i>This examples requires that javascript support is
enabled.</i>", Wt.XHTMLText, app.root());
pills = Wt.WContainerWidget(app.root());
pills.setContentAlignment(Wt.AlignCenter);
createDragImage("icons/blue-pill.jpg",
"icons/blue-pill-small.png",
"blue-pill", pills);
createDragImage("icons/red-pill.jpg",
"icons/red-pill-small.png",
"red-pill", pills);
dropSites = Wt.WContainerWidget(app.root())
Character("Neo", dropSites);
Character("Morpheus", dropSites);
Character("Trinity", dropSites);
app.useStyleSheet("dragdrop.css");
return app
