Typedef Documentation

v2dScrollerMove

typedef struct v2dScrollerMove v2dScrollerMove

Scrollers should behave in the following ways, when clicked on with LMB (and dragged):

1. 'Handles' on end of 'bubble' - when the axis that the scroller represents is zoomable, enlarge 'cur' rect on the relevant side.
2. 'Bubble'/'bar' - just drag, and bar should move with mouse (view pans opposite).

In order to make sure this works, each operator must define the following RNA-Operator Props:

• deltax, deltay - define how much to move view by (relative to zoom-correction factor)

v2dViewPanData

typedef struct v2dViewPanData v2dViewPanData

This group of operators come in several forms:

1. Modal 'dragging' with MMB - where movement of mouse dictates amount to pan view by
2. Scroll-wheel 'steps' - rolling mouse-wheel by one step moves view by predefined amount

In order to make sure this works, each operator must define the following RNA-Operator Props:

• deltax, deltay - define how much to move view by (relative to zoom-correction factor) Temporary custom-data for operator.

v2dViewZoomData

typedef struct v2dViewZoomData v2dViewZoomData

This group of operators come in several forms:

1. Scroll-wheel 'steps' - rolling mouse-wheel by one step zooms view by predefined amount.
2. Scroll-wheel 'steps' + alt + ctrl/shift - zooms view on one axis only (ctrl=x, shift=y). XXX this could be implemented...
3. Pad +/- Keys - pressing each key moves the zooms the view by a predefined amount.

In order to make sure this works, each operator must define the following RNA-Operator Props:

• zoomfacx, zoomfacy - These two zoom factors allow for non-uniform scaling. It is safe to scale by 0, as these factors are used to determine. amount to enlarge 'cur' by. Temporary custom-data for operator.

The user defines a rect using standard box select tools, and we use this rect to define the new zoom-level of the view in the following ways:

1. LEFTMOUSE - zoom in to view
2. RIGHTMOUSE - zoom out of view

Currently, these key mappings are hardcoded, but it shouldn't be too important to have custom keymappings for this...
