+# ImGuiDatePicker
+ImGuiDatePicker is a custom calendar-style date-picker widget for [Dear ImGui](https://github.com/ocornut/imgui) written in `C++20` that can easily be compiled alongside `ImGui` by adding the header and source files to your `ImGui` project.
+

+Font used: [Open Sans](https://fonts.google.com/specimen/Open+Sans)
+
+ImGuiDatePicker uses the `tm` struct for working with dates:
+``` C++
+struct tm
+{
+    int tm_sec;   // seconds after the minute - [0, 60] including leap second
+    int tm_min;   // minutes after the hour - [0, 59]
+    int tm_hour;  // hours since midnight - [0, 23]
+    int tm_mday;  // day of the month - [1, 31]
+    int tm_mon;   // months since January - [0, 11]
+    int tm_year;  // years since 1900
+    int tm_wday;  // days since Sunday - [0, 6]
+    int tm_yday;  // days since January 1 - [0, 365]
+    int tm_isdst; // daylight savings time flag
+};
+```
+## Including
+`IMGUI_DATEPICKER_YEAR_MIN` and `IMGUI_DATEPICKER_YEAR_MAX` should be defined before including [ImGuiDatePicker.hpp](ImGuiDatePicker.hpp). If they are not defined, they will default to `1900` and `3000` respectively.
+``` C++
+// Define the lowest year that the picker can select. In this example, '1970' is the Unix epoch.
+#define IMGUI_DATEPICKER_YEAR_MIN 1970
+// Define the highest year that the picker can select.
+#define IMGUI_DATEPICKER_YEAR_MAX 3000
+#include <ImGuiDatePicker.hpp>
+```
+## Usage
+``` C++
+// Get today's date and store it in a 'tm' struct named 't'
+std::chrono::system_clock::time_point now = std::chrono::system_clock::now();
+std::time_t currentTime = std::chrono::system_clock::to_time_t(now);
+tm t = *std::gmtime(&currentTime);
+
+// Use the picker
+if (ImGui::DatePicker("Date", t))
+{
+    // Perform some event whenever the date 't' is changed
+}
+```
+An `alt font` can also be supplied to the picker by calling `DatePickerEx`. This `alt font` will be used for the picker's days-of-the-week headers and for the month-picker combo box.
+``` C++
+ImFont* boldFont = GetBoldFontFromSomewhere();
+tm t = GetTmFromSomewhere();
+ImGui::DatePickerEx("Date", t, boldFont);
+```
