Hello,
I just found a fun bug in GTK2HS.
<span class='hs-definition'>panedAdd1</span> <span
class='hs-keyglyph'>::</span> <span class='hs-layout'>(</span><span
class='hs-conid'>PanedClass</span> <span class='hs-varid'>self</span><span
class='hs-layout'>,</span> <span class='hs-conid'>WidgetClass</span> <span
class='hs-varid'>child</span><span class='hs-layout'>)</span> <span
class='hs-keyglyph'>=></span> <span class='hs-varid'>self</span>
<a name='line-145'></a> <span class='hs-keyglyph'>-></span> <span
class='hs-varid'>child</span> <span class='hs-comment'>-- ^ @child@ - the child
to add</span>
<a name='line-146'></a> <span class='hs-keyglyph'>-></span> <span
class='hs-conid'>IO</span> <span class='hs-conid'>()</span>
should be:
<span class='hs-definition'>panedAdd1</span> <span
class='hs-keyglyph'>::</span> <span class='hs-layout'>(</span><span
class='hs-conid'>PanedClass</span> <span class='hs-varid'>self</span><span
class='hs-layout'>,</span> Container<span class='hs-conid'>Class</span> <span
class='hs-varid'>child</span><span class='hs-layout'>)</span> <span
class='hs-keyglyph'>=></span> <span class='hs-varid'>self</span>
<a name='line-145'></a> <span class='hs-keyglyph'>-></span> <span
class='hs-varid'>child</span> <span class='hs-comment'>-- ^ @child@ - the child
to add</span>
<a name='line-146'></a> <span class='hs-keyglyph'>-></span> <span
class='hs-conid'>IO</span> <span class='hs-conid'>()</span>
I found this, because I had a VBox that I used to pass directly to panedAdd
1.
Then after a remodularization I ended up calling castToWidget on said VBox.
This resulted in my VBox not being added to the Paned at all :(
Interestingly, simply doing castToContainer again didn't save me. I had to
create a new VBox to put my widgetized VBox into...
