Class: Wx::VScrolledWindow

Inherits:
Panel show all
Defined in:
lib/wx/doc/gen/v_scrolled_window.rb

Overview

In the name of this class, “V” may stand for “variable” because it can be used for scrolling rows of variable heights; “virtual”, because it is not necessary to know the heights of all rows in advance only those which are shown on the screen need to be measured; or even “vertical”, because this class only supports scrolling vertically.

In any case, this is a generalization of Scrolled which can be only used when all rows have the same heights. It lacks some other Scrolled features however, notably it can’t scroll specific pixel sizes of the window or its exact client area size. To use this class, you need to derive from it and implement the on_get_row_height pure virtual method. You also must call #set_row_count to let the base class know how many rows it should display, but from that moment on the scrolling is handled entirely by VScrolledWindow. You only need to draw the visible part of contents in your OnPaint() method as usual. You should use #get_visible_rows_begin and #get_visible_rows_end to select the lines to display. Note that the device context origin is not shifted so the first visible row always appears at the point (0, 0) in physical as well as logical coordinates.

wxWidgets 2.8 Compatibility Functions

The following functions provide backwards compatibility for applications originally built using VScrolledWindow in 2.6 or 2.8. Originally, VScrolledWindow referred to scrolling “lines”. We now use “units” in VarScrollHelperBase to avoid implying any orientation (since the functions are used for both horizontal and vertical scrolling in derived classes). And in the new VScrolledWindow and HScrolledWindow classes, we refer to them as “rows” and “columns”, respectively. This is to help clear some confusion in not only those classes, but also in HVScrolledWindow where functions are inherited from both. You are encouraged to update any existing code using these function to use the new replacements mentioned below, and avoid using these functions for any new code as they are deprecated.

size_t GetFirstVisibleLine() const Deprecated for #get_visible_rows_begin.

size_t GetLastVisibleLine() const Deprecated for #get_visible_rows_end. This function originally had a slight design flaw in that it was possible to return (size_t)-1 (ie: a large positive number) if the scroll position was 0 and the first line wasn’t completely visible.

size_t GetLineCount() const Deprecated for #get_row_count.

<code>int HitTest(wxCoord x, wxCoord y) const

int HitTest(const Wx::Point& pt) const</code> Deprecated for #virtual_hit_test.

virtual wxCoord OnGetLineHeight(size_t line) const Deprecated for on_get_row_height.

virtual void OnGetLinesHint(size_t lineMin, size_t lineMax) const Deprecated for on_get_rows_height_hint.

virtual void RefreshLine(size_t line) Deprecated for #refresh_row.

virtual void RefreshLines(size_t from, size_t to) Deprecated for #refresh_rows.

virtual bool ScrollLines(int lines) Deprecated for #scroll_rows.

virtual bool ScrollPages(int pages) Deprecated for #scroll_row_pages.

bool ScrollToLine(size_t line) Deprecated for #scroll_to_row.

void SetLineCount(size_t count) Deprecated for #set_row_count.

Constructor Details

#initialize ⇒ Wx::VScrolledWindow #initialize(parent, id = Wx::StandardID::ID_ANY, pos = Wx::DEFAULT_POSITION, size = Wx::DEFAULT_SIZE, style = 0, name = Wx::PANEL_NAME_STR) ⇒ Wx::VScrolledWindow

Returns a new instance of VScrolledWindow.

Overloads:

  • #initialize ⇒ Wx::VScrolledWindow

    Default constructor, you must call #create later.

  • #initialize(parent, id = Wx::StandardID::ID_ANY, pos = Wx::DEFAULT_POSITION, size = Wx::DEFAULT_SIZE, style = 0, name = Wx::PANEL_NAME_STR) ⇒ Wx::VScrolledWindow

    This is the normal constructor, no need to call #create after using this constructor.

    Note:

    Wx::VSCROLL is always automatically added to the style, there is no need to specify it explicitly.

    Parameters:

    • parent (Wx::Window) —

      The parent window, must not be NULL.

    • id (Integer) (defaults to: Wx::StandardID::ID_ANY) —

      The identifier of this window, StandardID::ID_ANY by default.

    • pos (Array(Integer, Integer), Wx::Point) (defaults to: Wx::DEFAULT_POSITION) —

      The initial window position.

    • size (Array(Integer, Integer), Wx::Size) (defaults to: Wx::DEFAULT_SIZE) —

      The initial window size.

    • style (Integer) (defaults to: 0) —

      The window style. There are no special style bits defined for this class.

    • name (String) (defaults to: Wx::PANEL_NAME_STR) —

      The name for this window; usually not used.

Instance Method Details

#calc_scrolled_position(coord) ⇒ Integer

Translates the logical coordinate given to the current device coordinate.

For example, if the window is scrolled 10 units and each scroll unit represents 10 device units (which may not be the case since this class allows for variable scroll unit sizes), a call to this function with a coordinate of 15 will return -85.

Parameters:

  • coord (Integer)

Returns:

  • (Integer)

See Also:



168
 
# File 'lib/wx/doc/gen/v_scrolled_window.rb', line 168

def calc_scrolled_position(coord) end

#calc_unscrolled_position(coord) ⇒ Integer

Translates the device coordinate given to the corresponding logical coordinate.

For example, if the window is scrolled 10 units and each scroll unit represents 10 device units (which may not be the case since this class allows for variable scroll unit sizes), a call to this function with a coordinate of 15 will return 115.

Parameters:

  • coord (Integer)

Returns:

  • (Integer)

def calc_unscrolled_position(coord) end

#create(parent, id = Wx::StandardID::ID_ANY, pos = Wx::DEFAULT_POSITION, size = Wx::DEFAULT_SIZE, style = 0, name = Wx::PANEL_NAME_STR) ⇒ Boolean

Same as the non-default constructor, but returns a status code: true if ok, false if the window couldn’t be created.

Just as with the constructor, the Wx::VSCROLL style is always used, there is no need to specify it explicitly.

Parameters:

  • parent (Wx::Window)
  • id (Integer) (defaults to: Wx::StandardID::ID_ANY)
  • pos (Array(Integer, Integer), Wx::Point) (defaults to: Wx::DEFAULT_POSITION)
  • size (Array(Integer, Integer), Wx::Size) (defaults to: Wx::DEFAULT_SIZE)
  • style (Integer) (defaults to: 0)
  • name (String) (defaults to: Wx::PANEL_NAME_STR)

Returns:

  • (Boolean)

def create(parent, id=Wx::StandardID::ID_ANY, pos=Wx::DEFAULT_POSITION, size=Wx::DEFAULT_SIZE, style=0, name=Wx::PANEL_NAME_STR) end

#enable_physical_scrolling(scrolling = true) ⇒ void

This method returns an undefined value.

With physical scrolling on (when this is true), the device origin is changed properly when a PaintDC is prepared, children are actually moved and laid out properly, and the contents of the window (pixels) are actually moved.

When this is false, you are responsible for repainting any invalidated areas of the window yourself to account for the new scroll position.

Parameters:

  • scrolling (Boolean) (defaults to: true)

Returns:

  • (Integer)

Returns:

  • (Integer)

def get_visible_begin; end

#get_visible_end ⇒ Integer Also known as: visible_end

Returns the index of the last visible unit based on the scroll position.

This includes the last unit even if it is only partially visible.

Returns:
