New CCalendarInputBox control element of the IncGUI library has been designed for date and/or time input.

• Custom Graphical Controls. Part 1: Creating a simple control
• Custom Graphical Controls. Part 2. Control Library
• Custom Graphical Controls. Part 3. Forms

CCalendarInputBox control element can be used in different modes: date and time input, date input, time input.

The time can be entered up to minutes or seconds (optional). Additionally Date and time can be amended by relocating the vertical line. In the normal state the element is a text field with the button. The tab is opened when the button is hit.

The tab with the numbered control elements is shown in the figure below.

Control element application starts from the Init() method call, the following parameters are indicated when the method is called:

• string aName="CCalendar" - control element name;
• bool aDate=true - if date input is used;
• bool aTime=true - if time input is used;
• bool aSeconds=true - time up to seconds;
• bool aLine=true - if the vertical line is enabled (additionally to date and/or time input);
• int aTimeMode=0 - current time type: 0 - terminal time, 2 - local time (time and date displayed at positions 13 and 15 of the figure above);
• string aCaption - label text near control element.

The current value is received using ValueDateTime() (in datetime format) and ValueString() (string in format). The time program set is executed using the SetValueDateTime() method.

In different modes (date/time input) the control element has different width that correpsonds to the length of a displayed value but the width can be changed using SetWidth() method. Control element uses the two interdependent classes CCalendar (not used independently) and CCalendarInputBox. Both classes are added to the IncGUI_v4.mqh file (attached).

Also, IncGUIv4mqh.chm file (IncGUI_v4.mqh library documentation) prepared in doxygen and eIncGUI_v4_Test_CCalendarInputBox.mq5 Expert Advisor with the example of the control element application are attached here.
