Hello - I'm using sc.UseTool() to draw horizontal lines at price levels. I set tool.BeginValue to the price at which I want to draw the line. That works fine. The line is drawn at that price, and the price value appears as text above the line. (Right aligned because I specify DT_RIGHT.) In my study, I want to optionally set a text label for the line instead of showing the price. By setting the tool.Text to the desired string, I can get the text label to display. HOWEVER, in the case where I display a text label, I want to suppress the price from showing as well. Is there a way to suppress the price display, while still enabling display of a text label? Thanks for any pointers. :) |

It is probably easier to have a separate string and use sc.UseTool() to draw that string. SCString LineRelatedInfo {""}; if (condition1) LineRelatedInfo.Format("this happens"); else LineRelatedInfo.Format(".2f", LinePrice); for the horizontal location, a string can be drawn anywhere from index 0 to sc.Index+124 Date Time Of Last Edit: 2022-08-26 04:05:25

Thank you for your suggestion. Later this evening I tried messing around with different combinations and found that this did what I wanted: To show just the text (right aligned on top of line): drawTool.DisplayHorizontalLineValue = 0;
drawTool.TextAlignment = DT_RIGHT | DT_TOP; drawTool.Text = "SAMPLE TEXT"; To show just the price (right aligned and on top of line): drawTool.DisplayHorizontalLineValue = 1;
drawTool.TextAlignment = DT_RIGHT | DT_TOP; drawTool.Text = ""; So I think this approach will meet my needs for the time being. Thank you again for checking my post and providing assistance! |
