Re: [Pythoncad-developer] Sytile and settings In new kernel

[Matteo B. <mat...@bo...>]

Hi Gertwing,

The night helps to keep the idea in mind :-)
So now I tell you how the new style will work.

The style object will be the same as I describe you in the last mail.
The style will be stored in the database as Entity in this way:
Entity('STYLE'.....) 

So each application will manage the style with the following method:
setApplicationStyle 
getApplicationStyle
getApplicationStyleList

To manage the document style you can use the following method:
getActiveStyle
setActiveStyle (if the style is a document style copy the style in the
document)
getStyleList
getStyle

The Entity will have the following new method:
getStyle
setStyle

so in case you have to render a segment :

from PyQt4 import QtCore, QtGui

class Segment(QtGui.QGraphicsLineItem):
    
    def __init__(self, entity):
        super(Segment, self).__init__()
        pt_begin = None
        pt_end = None
        # get the geometry
        geometry = entity.getConstructionElements()

	  stl=entity.getStyle() #*** <<<<<<<<<<<<<<<<<<<<<<<<<New method

        # get the begin and endpoint from the geometry
        for key in geometry.keys():
            if pt_begin == None:
                pt_begin = geometry[key]
            else:
                pt_end = geometry[key]
        # set the line
        self.setLine(pt_begin.x, -1.0 * pt_begin.y, pt_end.x, -1.0 *
pt_end.y)
        # set pen accoording to layer

	  color=Stl.getStyleProp("color") #*** <<<<<<<<<<<<<<<New Method

        self.setPen(QtGui.QPen(QtGui.QColor.fromRgb(color)))
        return

The user interface have to manage this style with a tree like (Just an
idea..)

	Application
		|-->Application Style
		|			|-->List of all the application
style
		|-->Active Document Style
					|-->List of all the active document
style

In a Bold or color will be indicated in the tree view the active style the
is currently set.
If the user would like to use a different style he just need to select if
from the tree view.

But we can discuss of this topic later when we will implements it on the
U/I.

Regards,
Matteo

Hi Matteo,

I don't have a clear view how these styles are applied to the elements
in the drawing.
In the database the elements have a relation with a layer, the layer
triggers how the elements are drawn.
So to draw the elements for each layer we need the properties color,
line style, thickness, etc.
Can you give an example how to retrieve the properties from the Style
object?

As I understand the style object is stored in the application
configuration and not in the drawing, is this correct?
What if the drawing contain layers that are not in the application
configuration?

Maybe you can give some more clarification.

Regards,
Gertwin
