Detailed Description
Interface for manipulating CaptionData objects.
- Todo:
- this could also be used for little sticky notes in the viewport, these would be text blocks that are not transformed with the viewport's matrix..
Member Function Documentation

Sets data=NULL.
That results in data->dec_count() being called somewhere along the line.
References Laxkit::anObject::dec_count().
|
virtual |
Return new CaptionInterface.
If dup!=NULL and it cannot be cast to CaptionInterface, then return NULL.
Reimplemented from LaxInterfaces::anInterface.

If !data on LBDown, then make a new one...
Get rid of old data if not clicking in it.
Reimplemented from LaxInterfaces::anInterface.

Create and return new data, also calls viewport->newData(newdata,0).
Please note that this function is not a redefinition of anything. It is used internally to get a new instance of CaptionData and also tell the viewport about it.
This function causes a new CaptionData to be created and to have a count of 2. Currently, new CaptionData makes the maxx/maxy be the image pixel width/height..
- Todo:
- need some flag somewhere to auto flip vertically (for +y is up rather than down)

Note that this calls imlib_context_set_drawable(dp->GetWindow()). Please note that Imlib does not naturally handle skewed fonts, and this function doesn't either.
Returns 1 if no data, -1 if thing was offscreen, or 0 if thing drawn.
- Todo:
- should work this to not need imlib, allowing a redefinable backend to render the text.

If mode==0, then edit existing text normally. If mode==1, then we are working on a brand new object. If the interface is called off without actually writing any text, then do not install the object.
