Returns: 'true' if defined, 'false' otherwise

Note: The apparent height is defined if either the region's absolute or relative height is explicitly specified (from set_height(), set_relative_height(), set_dimensions(), or set_relative_dimensions()), or if its left and right borders are anchored. A region with an undefined apparent height will not be rendered on the screen until its height is defined.

Definition at line 284 of file gui_region.cpp.

◆ is_apparent_width_defined()

bool lxgui::gui::region::is_apparent_width_defined ( ) const

inherited

Checks if this region's apparent width is defined.

Returns: 'true' if defined, 'false' otherwise

Note: The apparent width is defined if either the region's absolute or relative width is explicitly specified (from set_width(), set_relative_width(), set_dimensions(), or set_relative_dimensions()), or if its left and right borders are anchored. A region with an undefined apparent width will not be rendered on the screen until its width is defined.

Definition at line 280 of file gui_region.cpp.

◆ is_in_region()

bool lxgui::gui::region::is_in_region ( const vector2f & position ) const

virtualinherited

Checks if the provided coordinates are inside this region.

Parameters

position The coordinates to test

Returns: 'true' if the provided coordinates are inside this region

Reimplemented in lxgui::gui::slider, and lxgui::gui::frame.

Definition at line 288 of file gui_region.cpp.

◆ is_loaded()

bool lxgui::gui::region::is_loaded ( ) const

inherited

Checks if this region has been fully loaded.

Note: A region that is not fully loaded still has all its core attributes set, hence can be considered as "fully constructed" from a C++ point of view. However, semantically, the object may need further steps to be complete, as designed by the UI designer. Therefore, form the UI's point of view, a region is considered "complete" only if is_loaded() returns 'true' (see notifu_loaded()). Only then can the region, e.g., react to or generate events.

Definition at line 798 of file gui_region.cpp.

◆ is_manually_inherited()

bool lxgui::gui::region::is_manually_inherited ( ) const

inherited

Checks if this object is manually inherited.

Checks if this region is of a type equal or derived from the supplied region.

Returns: 'true' if this region is of a type equal or derived from the supplied region

Definition at line 431 of file gui_region.hpp.

◆ is_region_type() [3/3]

bool lxgui::gui::region::is_region_type ( const std::string & type_name ) const

◆ is_valid()

bool lxgui::gui::region::is_valid ( ) const

inherited

Checks if this region has all its borders correctly defined.

Returns: 'true' if this region has all its borders correctly defined

Note: To be valid, a region needs to have a defined position and size along both the X and Y dimensions. This means either one anchor and a set size, or two opposite anchors. For example, any anchor plus a call to set_dimensions(). Or a top_left plus a bottom_right anchors. Or a left plus a right anchors plus a call to set_height().

◆ parse_file_name()

std::string lxgui::gui::region::parse_file_name ( const std::string & file_name ) const

inherited

Convert an addon-relative file path to a application-relative path.

Parameters

file_name The raw file name

Note: All file names must be relative to the current working directory (typically, the application's executable path), but sometimes it is more convenient and maintainable to specify a path that is relative to the addon directory. This can be achieved by simply putting "|" in front of a file name, which will then be interpreted as relative to the addon directory. This function takes care of this transformation.
