Widget_Text & Scroll Bar on Linux and Windows 969 0
Started by Deleted User
I have this widget_text with scroll bars. Looks like when the text area is full and we append new text, the scroll bar scrolls to the bottom automatically on Linux. This is not the case on Windows, in which the scroll bar remains at the top, and to view newly appended text one has to manually scroll down. Is there a way to force the scroll to move to the bottom automatically The "set_text_top_line" does not accomplish this as it moves previous text upward.
Thank you,

Hi guys,
&160;&160;&160; I&160;am a new learner. I need a variable, which can be an array or anything, to contain 14 vectors with different lengths. if they are of equal length l, I can simply build an 14 * l array&160;
&160;&160;&160; I can&160;run a loop 14 times to process these vectors, but that is definitely nor a good solution.
Thanks for your advice
