PyImageList

A PyImageList contains a list of images. Images can have masks for transparent drawing, and can be made from a variety of sources including bitmaps and icons.

PyImageList is used in conjunction with UltimateListCtrl.

Note

The main improvements that PyImageList introduces is the removal of the limitation of same-size images inside the image list. If you use the style IL_VARIABLE_SIZE then each image can have any size (in terms of width and height).

Class API

class PyImageList(object)

A PyImageList contains a list of images. Images can have masks for transparent drawing, and can be made from a variety of sources including bitmaps and icons.

PyImageList is used in conjunction with UltimateListCtrl.

Note

The main improvements that PyImageList introduces is the removal of the limitation of same-size images inside the image list. If you use the style IL_VARIABLE_SIZE then each image can have any size (in terms of width and height).

---

__init__(width, height, mask=True, initialCount=1, style=IL_VARIABLE_SIZE)

Default class constructor.

Parameters:

• width – the width of the images in the image list, in pixels (unused if you specify the IL_VARIABLE_SIZE style;
• height – the height of the images in the image list, in pixels (unused if you specify the IL_VARIABLE_SIZE style;
• mask – True if masks should be created for all images (unused in PyImageList);
• initialCount – the initial size of the list (unused in PyImageList);
• style – can be one of the following bits:
  
  

  Style Flag	Value	Description
  IL_FIXED_SIZE	0	All the images in PyImageList have the same size (width, height)
  IL_VARIABLE_SIZE	1	Each image can have any size (in terms of width and height)

---

Add(bitmap)

Adds a new image or images using a bitmap.

Parameters:bitmap – a valid wx.Bitmap object. Returns:The new zero-based image index.

Note

If the bitmap is wider than the images in the list and you are not using the IL_VARIABLE_SIZE style, then the bitmap will automatically be split into smaller images, each matching the dimensions of the image list.

---

AddIcon(icon)

Adds a new image using an icon.

Parameters:icon – a valid wx.Icon object. Returns:The new zero-based image index.

Note

If the icon is wider than the images in the list and you are not using the IL_VARIABLE_SIZE style, then the icon will automatically be split into smaller images, each matching the dimensions of the image list.

---

AddWithColourMask(bitmap, maskColour)

Adds a new image or images using a bitmap and a colour mask.

Parameters:

• bitmap – a valid wx.Bitmap object;

• colour – an instance of wx.Colour, a colour indicating which parts of the image are transparent.

Returns:

The new zero-based image index.

Note

If the bitmap is wider than the images in the list and you are not using the IL_VARIABLE_SIZE style, then the bitmap will automatically be split into smaller images, each matching the dimensions of the image list.

---

Draw(index, dc, x, y, flags, solidBackground=True)

Draws a specified image onto a device context.

Parameters:

• index – the image index, starting from zero;
• dc – an instance of wx.DC;
• x – x position on the device context;
• y – y position on the device context;
• flags – how to draw the image. A bitlist of a selection of the following:
  
  

  Flag Paarameter	Description
  wx.IMAGELIST_DRAW_NORMAL	Draw the image normally
  wx.IMAGELIST_DRAW_TRANSPARENT	Draw the image with transparency
  wx.IMAGELIST_DRAW_SELECTED	Draw the image in selected state
  wx.IMAGELIST_DRAW_FOCUSED	Draw the image in a focused state

• solidBackground – currently unused.

---

GetBitmap(index)

Returns the bitmap corresponding to the given index, or wx.NullBitmap if the index is invalid.

Parameters:index – the bitmap index.

---

GetIcon(index)

Returns the icon corresponding to the given index, or wx.NullIcon if the index is invalid.

Parameters:index – the icon index.

---

GetImageCount()

Returns the number of images in the list.

---

GetSize(index)

Retrieves the size of an image in the list.

Parameters:index – the zero-based index of the image. Returns:a tuple of (width, height) properties of the chosen bitmap.

---

Remove(index)

Removes the image at the given position.

Parameters:index – the zero-based index of the image to be removed.

---

RemoveAll()

Removes all the images in the list.

---

Replace(index, bitmap)

Replaces the existing image with the new bitmap.

Parameters:

• index – the index at which the image should be replaced;
• bitmap – the new bitmap to add to the image list, an instance of wx.Bitmap.

---

ReplaceIcon(index, icon)

Replaces the existing image with the new icon.

Parameters:

• index – the index at which the image should be replaced;
• icon – the new icon to add to the image list, an instance of wx.Icon.
