ToolResizeData Struct Reference

#include <c4d_baselist.h>

Detailed Description

Message struct for the MSG_TOOL_RESIZE message.
Sent during MMB (Middle Mouse Button) dragging and the [ and ] shortcuts with brushes if ToolAskMsgData::resize_allowed is set to true by the developer.
Here is an example from the Live Selection tool to show how it works:

Bool LiveSelectionTool::Message(BaseDocument *doc, BaseContainer &data, Int32 type, void *t_data)
{
  switch (type)
  {
  case MSG_TOOL_ASK:
  {
    ToolAskMsgData *a = (ToolAskMsgData*)t_data;
    a->resize_allowed = true;
  }
  break;
  case MSG_TOOL_RESIZE:
  {
    ToolResizeData *d = (ToolResizeData*)t_data;
    if (!d || !d->data)
      return false;
    switch (d->pass)
    {
    case ToolResizeData::RESIZE_PASS_INIT:
    {
      d->falloff.show = d->cross_type = d->data->GetInt32(MDATA_SELECTLIVE_MODE) != MDATA_SELECTLIVE_MODE_NORMAL;
      d->falloff.size = d->data->GetFloat(MDATA_SELECTLIVE_RADIUS);
      d->falloff.opacity = d->data->GetFloat(MDATA_SOFT_STRENGTH);
      d->falloff.position.off = Vector(mousex, mousey, 0.0);
    }
    break;
    case ToolResizeData::RESIZE_PASS_RESIZE:
    {
      if (d->horizontal)
      {
        d->falloff.size = d->data->GetFloat(MDATA_SELECTLIVE_RADIUS);
        d->falloff.size += d->delta;
        if (d->falloff.size < 0.0) d->falloff.size = 0.0;
        if (d->falloff.size > 1000.0) d->falloff.size = 1000.0;
        d->data->SetFloat(MDATA_SELECTLIVE_RADIUS, d->falloff.size);
      }
      else
      {
        if (d->data->GetInt32(MDATA_SELECTLIVE_MODE) == MDATA_SELECTLIVE_MODE_SOFTSELECTION)
        {
          d->falloff.opacity = d->data->GetFloat(MDATA_SOFT_STRENGTH);
          d->falloff.opacity += Float(d->delta) * 0.01;
          d->falloff.opacity = FCut(d->falloff.opacity, 0.0, 1.0);
          d->data->SetFloat(MDATA_SOFT_STRENGTH, d->falloff.opacity);
        }
        else
        {
          d->falloff.opacity = d->data->GetFloat(MDATA_VERTEXPAINT_STRENGTH);
          d->falloff.opacity += Float(d->delta) * 0.01;
          d->falloff.opacity = FCut(d->falloff.opacity, 0.0, 1.0);
          d->data->SetFloat(MDATA_VERTEXPAINT_STRENGTH, d->falloff.opacity);
        }
      }
    }
    break;
    default: break;
    }
  }
  break;
  }
 
  ...
}

Constructor & Destructor Documentation

ToolResizeData()

ToolResizeData

(

)

Default constructor.

Member Data Documentation

pass

enum ToolResizeData::RESIZE_PASS pass

[Read-Only]
The resize pass: RESIZE_PASS

delta

Int32 delta

[Read-Only]
The mouse movement delta.

total_delta

Int32 total_delta

[Read-Only]
The mouse movement delta.

horizontal

Int32 horizontal

[Read-Only]
true if a horizontal movement is occurring and cross_type has been set to true in the RESIZE_PASS_INIT pass by the user.

data

BaseContainer* data

[Read-Only]
A pointer to the tool's BaseContainer.

cross_type

Bool cross_type

Set to false to disable cross type resizing, where the primary direction the mouse is moved in dictates movement afterwards.

falloff

ToolResizeFalloffData falloff

The radial falloff display preview settings.

cursor_text

String cursor_text

The text to display next to the mouse cursor.
