Detailed Description

cpp

class Theme;

Application Theme holding custom style variables that override the current ImGui style and/or are used separately by various parts of the I3T code.

The Theme holds color information as well as general sizing information.

Themes do have a UI/DPI scaling factor using which relevant sizing variables are scaled when fetched. Changes of the scaling factor are however handled elsewhere (in UIModule).

Themes do hold an association between font keys and actual font names. But fonts are loaded and managed externally (by the FontManager). Currently the Theme cannot load new fonts, but it can change which fonts are used where. // Proposal: (Issue #432) Themes could tell FontManager which fonts to load

using Colors

cpp

using Theme::Colors =  std::unordered_map<EColor, ImVec4>;

using Sizes

cpp

using Theme::Sizes =  std::unordered_map<ESize, std::pair<float, bool> >;

Map of ESizeVec2 and a pair of float and bool, bool specifies whether the float is dpi scaled.

using SizesVec

cpp

using Theme::SizesVec =  std::unordered_map<ESizeVec2, std::pair<ImVec2, bool> >;

Map of ESizeVec2 and a pair of ImVec2 and bool, bool specifies whether the ImVec2 is dpi scaled.
