Customised ToolTips in AddOn

[jeronymite]

I'm hesitant to post this, since it is most likely a C# WPF oddity I'm ignorant of. Nevertheless, since it remotely might be related to how NinjaTrader 8 has implemented things ... or a generous soul may answer the generic question in any case ...

In the code of an AddOn, I'm trying to create and customise ToolTips for various objects -- Button, Label, etc. I want to change the Font characteristics (FontSize, FontFamily, etc) of the ToolTip dynamically.

I have tried creating a new ToolTip object and adjusting those Properties on it, then setting the target object's ToolTip to the modified ToolTip, but those Properties are not changed when the ToolTip displays.

I have tried using ToolTipService to SetToolTip to see if that affects anything -- it doesn't; although, I can change the ShowDuration with ToolTipService, so that is one win.

Any advice would be most gratefully received.

Thanks.

Hello jeronymite,

Thanks for the post.

I don't have a sample of a tool tip to try however it is very likely that you need to set the controls style to null. The platform uses custom skins which will apply to most WPF controls. If you need to set custom values you will need to do that either from the skin, after the object is displayed(in some cases) or using a null style on the control.

If you are using C# it would be myTooltipVariable.Style = null;
For xaml it would be <MyTooltipControl Style="{x:Null}" />


If that does not help and you can post a small sample that shows the tooltip in some way we could explore that further.

I look forward to being of further assistance.
