Class: Wx::HScrolledWindow

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

Overview

In the name of this class, “H” stands for “horizontal” because it can be used for scrolling columns of variable widths.

It is not necessary to know the widths of all columns in advance only those which are shown on the screen need to be measured. In any case, this is a generalization of Scrolled which can be only used when all columns have the same widths. 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_column_width pure virtual method. You also must call #set_column_count to let the base class know how many columns it should display, but from that moment on the scrolling is handled entirely by HScrolledWindow. You only need to draw the visible part of contents in your OnPaint() method as usual. You should use #get_visible_columns_begin and #get_visible_columns_end to select the lines to display. Note that the device context origin is not shifted so the first visible column always appears at the point (0, 0) in physical as well as logical coordinates.

Constructor Details

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

Returns a new instance of HScrolledWindow.

Overloads:

  • #initialize ⇒ Wx::HScrolledWindow

    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::HScrolledWindow

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

    Note:

    Wx::HSCROLL 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 nil.

    • 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

#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::HSCROLL 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)

# File 'lib/wx/doc/gen/hv_scrolled_window.rb', line 600

def enable_physical_scrolling(scrolling=true) end

#get_column_count ⇒ Integer Also known as: column_count

Returns the number of columns the target window contains.

Returns:

  • (Integer)

534
 
# File 'lib/wx/doc/gen/hv_scrolled_window.rb', line 534

def get_column_count; end

#get_visible_begin ⇒ Integer Also known as: visible_begin

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

Returns:

  • (Integer) 


604
 
# File 'lib/wx/doc/gen/hv_scrolled_window.rb', line 604

def get_visible_begin; end

#get_visible_columns_begin ⇒ Integer Also known as: visible_columns_begin

Returns the index of the first visible column based on the scroll position.

Returns:

  • (Integer)

# File 'lib/wx/doc/gen/hv_scrolled_window.rb', line 539

def get_visible_columns_begin; end

#get_visible_columns_end ⇒ Integer Also known as: visible_columns_end

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

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

Returns:

  • (Integer) 


546
 
# File 'lib/wx/doc/gen/hv_scrolled_window.rb', line 546

def get_visible_columns_end; 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:

  • (Integer) 


611
 
# File 'lib/wx/doc/gen/hv_scrolled_window.rb', line 611

def get_visible_end; end

#is_column_visible(column) ⇒ Boolean Also known as: column_visible?

Returns true if the given column is currently visible (even if only partially visible) or false otherwise.

Parameters:

  • column (Integer)

Returns:

  • (Boolean) 


552
 
# File 'lib/wx/doc/gen/hv_scrolled_window.rb', line 552

def is_column_visible(column) end

#is_visible(unit) ⇒ Boolean Also known as: visible?

Returns true if the given scroll unit is currently visible (even if only partially visible) or false otherwise.

Parameters:

  • unit (Integer)

Returns:

  • (Boolean) 


617
 
# File 'lib/wx/doc/gen/hv_scrolled_window.rb', line 617

def is_visible(unit) end

#on_get_column_width(column) ⇒ Integer (protected)

This function must be overridden in the derived class, and should return the width of the given column in pixels.

Parameters:

  • column (Integer)

Returns:

  • (Integer) 


642
 
# File 'lib/wx/doc/gen/hv_scrolled_window.rb', line 642

def on_get_column_width(column) end

#on_get_columns_width_hint(columnMin, columnMax) ⇒ void (protected)

This method returns an undefined value.

This function doesn’t have to be overridden but it may be useful to do so if calculating the columns’ sizes is a relatively expensive operation as it gives your code a chance to calculate several of them at once and cache the result if necessary.

#on_get_columns_width_hint is normally called just before #on_get_column_width but you shouldn’t rely on the latter being called for all columns in the interval specified here. It is also possible that #on_get_column_width will be called for units outside of this interval, so this is really just a hint, not a promise. Finally, note that columnMin is inclusive, while columnMax is exclusive.

Parameters:

  • columnMin (Integer)
  • columnMax (Integer) 


637
 
# File 'lib/wx/doc/gen/hv_scrolled_window.rb', line 637

def on_get_columns_width_hint(columnMin, columnMax) end

#refresh_column(column) ⇒ void

This method returns an undefined value.

Triggers a refresh for just the given column’s area of the window if it’s visible.

Parameters:

  • column (Integer)
