Detailed Description

Base class for creating containers with one or two scrollbar(s).

For now users can't instanciate this class directly and needs to use small wrapper classes. Maybe in the future users can use the class directly.

Todo:
events are not yet send to the content grid.

Definition at line 41 of file scrollbar_container.hpp.

Member Enumeration Documentation

The way to handle the showing or hiding of the scrollbar.

Enumerator
always_visible 

The scrollbar is always shown, whether needed or not.

always_invisible 

The scrollbar is never shown even not when needed.

There's also no space reserved for the scrollbar.

auto_visible 

The scrollbar is shown when the number of items is larger as the visible items.

The space for the scrollbar is always reserved, just in case it's needed after the initial sizing (due to adding items).

auto_visible_first_run 

Like auto_visible, but when not needed upon the initial layout phase, the bars are not shown and no space is reserved for them.

(The algorithm hides them by default.

Definition at line 62 of file scrollbar_container.hpp.

Possible states of the widget.

Note the order of the states must be the same as defined in settings.hpp.

Enumerator
ENABLED 
DISABLED 
COUNT

const int  width_modification_pos 
)
private
bool gui2::tscrollbar_container::content_resize_request ( const bool  force_sizing = false)
protected

Notification if the content of a child needs a resize.

When a resize is required the container first can try to handle it itself. If it can't honor the request the function will call twindow::invalidate_layout().

Note
Calling this function on a widget with size == (0, 0) results false but doesn't call invalidate_layout, the engine expects to be in build up phase with the layout already invalidated.
Parameters
force_sizingIf the contents fit do we want to force a resize? This is needed in the MP lobby since items might not be properly placed yet. (The listboxes with the player info need it.)
Returns
True if the resize is handled, false otherwise.
Todo:
Try to handle auto_visible_first_run here as well.

Handling it here makes the code a bit more complex but allows to not reserve space for scrollbars, which will look nicer in the MP lobby. But the extra complexity is no 1.8 material.

bool gui2::tscrollbar_container::content_resize_request ( const int  width_modification,
const int  height_modification,
const int  width_modification_pos = -1,
const int  height_modification_pos = -1 
)
protected

Request from the content to modify the size of the container.

When the wanted resize fails the function will call twindow::invalidate_layout().

Note
Calling this function on a widget with size == (0, 0) results false but doesn't call invalidate_layout, the engine expects to be in build up phase with the layout already invalidated.
If twindow::get_need_layout() is true the function returns false and doesn't try to fit the contents since a layout phase will be triggered anyway.
This function might replace the content_resize_request above.
Parameters
width_modificationThe wanted modification to the width:
  • negative values reduce width.
  • zero leave width as is.
  • positive values increase width.
height_modificationThe wanted modification to the height:
  • negative values reduce height.
  • zero leave height as is.
  • positive values increase height.
width_modification_posThe position where the additional content was inserted/removed, defaults to -1 whcih means 'at end'
height_modification_poThe position where the additional content was inserted/removed, defaults to -1 whcih means 'at end'
Returns
True is wanted modification is accepted false otherwise.
