Functions Documentation ​

function Button ​

cpp
bool Button(
    const char * id,
    bool disabled,
    const ImVec2 & size
)

function ButtonWithCorners ​

cpp
bool ButtonWithCorners(
    const char * label,
    ImDrawFlags corners,
    const ImVec2 & size_arg
)

function ButtonWithCornersEx ​

cpp
bool ButtonWithCornersEx(
    const char * label,
    ImDrawFlags corners,
    const ImVec2 & size_arg,
    ImGuiButtonFlags flags
)

function calculateDataItemsWidth ​

cpp
float calculateDataItemsWidth(
    float fontSize,
    int maxCharacters,
    float zoom =1.0f
)

Works out pixel width of data items based on the provided parameters.

Parameters:

  • fontSize Current font size in pixels
  • maxCharacters Max number of characters/numerals any data item value has
  • zoom Zoom/scaling level

Return: The desired data item width in pixels

function convertCoordinates ​

cpp
inline glm::vec2 convertCoordinates(
    glm::vec2 position,

function DimButton ​

cpp
bool DimButton(

function dockTabStylePop ​

cpp
void dockTabStylePop()

function dockTabStylePush ​

cpp
void dockTabStylePush()

Sets style for the tab of a dockable window.

This method should be called after the ImGui::Begin call of a dockable window. Style needs to be popped afterwards with dockTabStylePop() Note that this style affects regular ImGui tabs, the style needs to be popped before using those in the dockable window.

By default, the standard tooltip settings are applied. Tooltip hover options can be modifed, for example to make the tooltip appearing delay longer: hoverFlags = ImGuiHoveredFlags_DelayNormal | ImGuiHoveredFlags_Stationary Tooltip hover delay (what normal / short delay means) can be set in ImGuiStyle.
