Hi Tung,
Thank you for writing back.
I am glad that setting the MinimumSize fits well your local setup.
As observed double clicking on the tab strip floats a
DocumentWindow as well as a
ToolWindow. When the window is floating double clicking the tab strip docks only the tool windows. Please note that this behavior is intended.
I agree that the documentation article stating that the title-bar should be double clicked might be not entirely precise. The double click should be performed on the tab strip item located in the
ToolTabStrip. Double clicking on the form`s title bar will maximize the window which is expected.
The document windows can be floated, tabbed, or docked. Please check the following documentation article:
The code snippet below shows how you can achieve docking a floating document window by double-clicking on the tab strip item located in the
DocumentTabStrip. I am also attaching a short video showing the result on my end.
Please note that docking a document window will dock it in the document container. If it fits better your local setup you can choose to use the DockState.
Tabbed setting which will display the window as a tabbed document.
Regarding your last question, the described behavior depends on how your layout has been arranged and where your document windows are docked. Please refer to the attached video file showing the dock layout.
I hope this information was useful. Should you have further questions please do not hesitate to write back.
Regards,
Hristo
