Where are my styles?

[lt.col.blair 0]

Hi,

I'm pretty new to FMX-Development and just trying to understand styles and how to change them.

I have a small application with two forms and a data module. On the datamodule i placed a stylebook component. The forms have that stylebook assigned in their StyleBook property.

If I open a form in the designer when the DataModule is not open, all contols are displayed without styling. As soon as I open the DataModule, the controls are styled. OK so far.

Some of the controls have their own StyleLookup assigned, e.g. "pnlWait". When I right click on that control and select "Edit user defined style", the style Edtor shows that style for editing:

But when I double click the StyleBook, that is placed on the DataSet to edit its styles, it is completely empty!

I could not find any Style settings in the .fmx or .dfm files.

Where are those styles stored?

I'm afraid to lose my styles, if I move my project and forget to take that special file along.

 

Also: I don't understand the difference between "StyleLookup" and "StyleName".  Right now I write the name of my changed styles into "StyleGrouping" and it seems to work, but even though I can copy that style to other controls by writing the name there, I can't select my styles never show up in the selection list ??

I would be glad, if anybody could point me to some tutorials that explain, how styles, style lookup and style name work together and how they get connected to controls. 

 

Thanks,Lutz

Set UseStyleManager to true of StyleBook to avoid this. Note : Only one TStyleBook can be set.

for exemple :   put a Tpath  and a panel on a form, fill the tpath with some data and set stylename to i.e. 'mytpath'
                      now set panel.stylelookup to 'mytpath'  and you will have your response

Ok, but did you pay attention to platform ? Have a look at platform 'default' and others if any in stylebook.styles collection

Ho ! You surely miss it because it's in "binary format"
 

 object StyleBook1: TStyleBook
    Styles = <
      item
        ResourcesBin = {
          464D585F5354594C4520322E350106125370656564427574746F6E315374796C

      }     

 end
      item
        Platform = 'Windows 10 Desktop'
        ResourcesBin = {
          464D585F5354594C4520322E3501060D427574746F6E315374796C6531039B0F

Sorry for the late reply but: THANK YOU. That helped me a lot. Slowly I'm beginning to understand
