[glade--]Fix for set_size_request

[Mark Jones <mark jones106 verizon net>]

I looked into this tonight.  There are two things missing related to size and positioning (that I see):

1.  Set size request not written.  The source of this is in: writers/widget.cc (line 85)

void Gtk_Widget::Configure(const Widget &w, CxxFile &f,const std::string &instance) const
{ 

....some lines of code here
// then:
  WriteIntIntProperty(w,f,instance, "width", "height", 
  	GTKMM2?"size_request":"usize");
// Should be:
  WriteIntIntProperty(w,f,instance, GTKMM2?"width_request":"width", GTKMM2?"height_request":"height", 
  	GTKMM2?"size_request":"usize");

With this change it works for Gtkmm2.

But, it needs to have the call to Fixed::put give the right values of x and y for a widget on a fixed container.  Right now it prints 0 and 0.  However, if you change the .glade file around a little, it then works.  So perhaps it is not reading the .glade file correctly?

Old glade section (glade-- prints 0's):
	      <child>
		<widget class="GtkSpinButton" id="spinbutton1">
		  <property name="width_request">112</property>
		  <property name="height_request">32</property>
		  <property name="visible">True</property>
		  <property name="can_focus">True</property>
		  <property name="climb_rate">1</property>
		  <property name="digits">0</property>
		  <property name="numeric">False</property>
		  <property name="update_policy">GTK_UPDATE_ALWAYS</property>
		  <property name="snap_to_ticks">False</property>
		  <property name="wrap">False</property>
		  <property name="adjustment">1 0 100 1 10 10</property>
		</widget>
		<packing>
		  <property name="x">8</property>
		  <property name="y">80</property>
		</packing>
	      </child>


Alternate glade section (glade-- prints the correct values for x and y):
	      <child>
		<widget class="GtkSpinButton" id="spinbutton1">
		  <property name="width_request">112</property>
		  <property name="height_request">32</property>
		  <property name="visible">True</property>
		  <property name="can_focus">True</property>
		  <property name="climb_rate">1</property>
		  <property name="digits">0</property>
		  <property name="numeric">False</property>
		  <property name="update_policy">GTK_UPDATE_ALWAYS</property>
		  <property name="snap_to_ticks">False</property>
		  <property name="wrap">False</property>
		  <property name="adjustment">1 0 100 1 10 10</property>
		  <property name="x">8</property>
		  <property name="y">80</property>
		</widget>
		<packing>
		  <property name="x">8</property>
		  <property name="y">80</property>
		</packing>
	      </child>


You'll notice I just copied the properties out of the packing section to the section above.  Then it finds them as properties when it looks for them in writers/fixed.cc:
void Gtk_Fixed::AddChild(const Widget &w,CxxFile &f,const std::string &instance) const
{  int x=w.getIntProperty("x",0);
   int y=w.getIntProperty("y",0);

I am not sure what is wrong here, whether glade is writing the xml wrong, or whether glade-- is not parsing it right, or if the code above should call something other than getIntProperty().

The line of code it produces in the whatever_glade.cc file is (in case that was not clear):
   fixed1->put(*spinbutton1, 8, 80);
