Checking the status of the main window
The pair of functions ChartSetInteger/ChartGetInteger allows you to find out some of the chart state characteristics, as well as change some of them.
Identifier |
Description |
Value type |
|---|---|---|
CHART_BRING_TO_TOP |
Chart activity (input focus) on top of all others |
bool |
CHART_IS_MAXIMIZED |
Chart maximized |
bool |
CHART_IS_MINIMIZED |
Chart minimized |
bool |
CHART_WINDOW_HANDLE |
Windows-handle of the chart window (r/o) |
int |
CHART_IS_OBJECT |
A flag that a chart is a Chart object (OBJ_CHART); true is for a graphic object and false is for a normal chart (r/o) |
bool |
As expected, the Window handle and the attribute of the chart object are read-only. Other properties are editable: for example, by calling ChartSetInteger(ID, CHART_BRING_TO_TOP, true), you activate the chart with the specified ID.
An example of applying properties is given in the ChartList4.mq5 script in the next section.
