class wx.html.HtmlContainerCell(HtmlCell)

Possible constructors:

HtmlContainerCell(parent)

The HtmlContainerCell class is an implementation of a cell that may contain more cells in it.

Methods

---

__init__(self, parent)

Constructor.

parent is pointer to parent container or None.

Parameters:parent (wx.html.HtmlContainerCell) –

---

GetAlignHor(self)

Returns container’s horizontal alignment.

Return type:int

---

GetAlignVer(self)

Returns container’s vertical alignment.

Return type:int

---

GetBackgroundColour(self)

Returns the background colour of the container or NullColour if no background colour is set.

Return type:Colour

---

GetIndent(self, ind)

Returns the indentation.

ind is one of the HTML_INDENT_ constants.

Parameters:ind (int) – Return type:int

Note

You must call GetIndentUnits with same ind parameter in order to correctly interpret the returned integer value. It is NOT always in pixels!

---

GetIndentUnits(self, ind)

Returns the units of indentation for ind where ind is one of the HTML_INDENT_ constants.

Parameters:ind (int) – Return type:int

---

InsertCell(self, cell)

Inserts a new cell into the container.

Parameters:cell (wx.html.HtmlCell) –

---

SetAlign(self, tag)

Sets the container’s alignment (both horizontal and vertical) according to the values stored in tag.

(Tags ALIGN parameter is extracted.) In fact it is only a front-end to SetAlignHor and SetAlignVer .

Parameters:tag (wx.html.HtmlTag) –

---

SetAlignHor(self, al)

Sets the container’s horizontal alignment.

During wx.html.HtmlCell.Layout each line is aligned according to al value.

Parameters:al (int) – new horizontal alignment. May be one of these values:

• wx.html.HTML_ALIGN_LEFT: lines are left-aligned (default)
• wx.html.HTML_ALIGN_JUSTIFY: lines are justified
• wx.html.HTML_ALIGN_CENTER: lines are centered
• wx.html.HTML_ALIGN_RIGHT: lines are right-aligned

---

SetAlignVer(self, al)

Sets the container’s vertical alignment.

This is per-line alignment!

Parameters:al (int) – new vertical alignment. May be one of these values:

• wx.html.HTML_ALIGN_BOTTOM: cells are over the line (default)
• wx.html.HTML_ALIGN_CENTER: cells are centered on line
• wx.html.HTML_ALIGN_TOP: cells are under the line

---

SetBackgroundColour(self, clr)

Sets the background colour for this container.

Parameters:clr (wx.Colour) –

---

SetBorder(self, clr1, clr2, border=1)

Sets the border (frame) colours.

A border is a rectangle around the container.

Parameters:

• clr1 (wx.Colour) – Colour of top and left lines
• clr2 (wx.Colour) – Colour of bottom and right lines
• border (int) – Size of the border in pixels

---

SetIndent(self, i, what, units=HTML_UNITS_PIXELS)

Sets the indentation (free space between borders of container and subcells).

Parameters:

• i (int) – Indentation value.
• what (int) – Determines which of the four borders we’re setting. It is wx.OR combination of following constants:
  • wx.html.HTML_INDENT_TOP: top border
  • wx.html.HTML_INDENT_BOTTOM: bottom
  • wx.html.HTML_INDENT_LEFT: left
  • wx.html.HTML_INDENT_RIGHT: right
  • wx.html.HTML_INDENT_HORIZONTAL: left and right
  • wx.html.HTML_INDENT_VERTICAL: top and bottom
  • wx.html.HTML_INDENT_ALL: all 4 borders
• units (int) – Units of i. This parameter affects interpretation of value.
  • wx.html.HTML_UNITS_PIXELS: i is number of pixels
  • wx.html.HTML_UNITS_PERCENT: i is interpreted as percents of width of parent container

---

SetMinHeight(self, h, align=HTML_ALIGN_TOP)

Sets minimal height of the container.

When container’s wx.html.HtmlCell.Layout is called, m_Height is set depending on layout of subcells to the height of area covered by layed-out subcells. Calling this method guarantees you that the height of container is never smaller than h - even if the subcells cover much smaller area.

Parameters:

• h (int) – The minimal height.
• align (int) – If height of the container is lower than the minimum height, empty space must be inserted somewhere in order to ensure minimal height. This parameter is one of HTML_ALIGN_TOP , HTML_ALIGN_BOTTOM , HTML_ALIGN_CENTER . It refers to the contents, not to the empty place.

---

SetWidthFloat(self, *args, **kw)

Overloaded Implementations:

---

SetWidthFloat (self, w, units)

Sets floating width adjustment.

The normal behaviour of container is that its width is the same as the width of parent container (and thus you can have only one sub-container per line). You can change this by setting the floating width adjustment.

Parameters:

• w (int) – Width of the container. If the value is negative it means complement to full width of parent container. E.g.:

  SetWidthFloat(-50, wx.html.HTML_UNITS_PIXELS)
  

  sets the width of container to parent’s width minus 50 pixels. This is useful when creating tables - you can call SetWidthFloat(50) and SetWidthFloat(-50).

• units (int) – Units of w This parameter affects the interpretation of value.
  • wx.html.HTML_UNITS_PIXELS: w is number of pixels
  • wx.html.HTML_UNITS_PERCENT: w is interpreted as percents of width of parent container

---

SetWidthFloat (self, tag, pixel_scale=1.0)

Sets floating width adjustment.

The normal behaviour of container is that its width is the same as the width of parent container (and thus you can have only one sub-container per line). You can change this by setting the floating width adjustment.

Parameters:

• tag (wx.html.HtmlTag) – In the second version of method, w and units info is extracted from tag’s WIDTH parameter.
• pixel_scale (float) – This is number of real pixels that equals to 1 HTML pixel.
