I need to add a title bar named "Crop Image" in this Cocoapod.
Please help me
I'm the developer of TOCropViewController. :)
There's no feature in the library at the moment to display text above the cropping content right now. But it would be fairly trivial to add a UILabel to the view and position it near the top of the view.
The challenge is that you'd then need to account for it when the device is rotated sideways. At the moment, the cropping content will fill the entire height of a horizontal device, so you'd need to override that to account for the text.
It's been a while since I wrote it, but I did include a property in the vertical layout code to add padding to the top of the view controller, so it SHOULD be relatively easy.
I sadly don't have time to add it myself, but I made an issue on the repo and added the pr requested tag. Hopefully someone with more free time than I do can add it. :)

I am building a leaderboard screen in the flutter application, whenever the user comes to the leaderboard screen, I want to show the animation of his old position to a new position in the leaderboard, so I need an animation of this row to go up or down based on his standings, please someone help me which widget to use to get this functionality working. Thanks
AnimatedList is the widget you are looking for. It automatically generates entrance and exit animation when items are added/deleted. Combined that with SizeTransition, and you will get a nice "growing/shrinking" effect.
There are some really good examples (and even a video tutorial) on the official docs as well.
You can also look at this answer for a more complex example of using 2 of them.
please check this picture first:
as you see, there are some distance from status bar.
if I want to put the highlight texts to this place,I have to add a fixaul padding to a view,
but if user is using a small screen device, will it out of screen?
is there any safe way to put a text away from status bar?
thanks for your help. have a nice day :)
Tableview separation by section content wise. Is possible to do that. I have attache a screen shot below. Please help me any one have idea about that.
I'm making my own UI from scratch using OpenGL that is why I'm asking this and please don't make any discouragement as this is just a hobby project.
Currently, I'm stuck implementing how this scrollbars really work. In my current implementation, the content scrolls at the wrong step value as well as the thumb, meaning, I set the value manually like 1px step for each of them.
The structure of my scrollbar implementation is describe as follows:
I draw scrollbars i.e the main rectangle where the 3 button lies.
Those 3 buttons are, thumb, buttonBack and buttonNext.
All of them do the basic logic of scrollbars i.e when I click each one of them, they moved. But the whole part(scrollbar) don't know how to scroll contents
So what I did is: I make another object and I call it scrollarea
It has two scrollbars, vertical and horizontal scrollbar.
I made a function called scrollToX and scrollToY which
does what I named to them.
But the step values I set to them are
manually set up.
I try to google some scrollbar, scrollarea, scrollview or whatever you call to that scrollable rectangle thing, but all I see are implementation and I cannot find any guides how to build your own. I have no choice but to look at their implementation. I try my best to comprehend what they did but their implementation of how their whole UI structure is very different to mine, and I cannot find anything useful there.
So I ask again here if anybody can explain me well how to make a properly functional scrollbar.
Most specific things I'm really concerned of are:
How do I determine the thumb step value?
How do I determine the content step value?
All of these depend on your content -
Is it just an image ? If so, you only need to change the offset depending on the size of the image.
Is it a list of values like in Windows explorer ? Then you need to create a data structure first that contains all of it, and shows the content that fits within the window as it scrolls.
OpenGL does not fit into this discussion.
I often use a TPanel or TGroupBox to group my form controls.
Now I need to draw just a straight line like the border of a Panel or GroupBox.
How do I do this on LAZARUS?
Thanks in advance!
Note: The technique must work on both Linux and Windows
As an optical line separator you should use either the TBevel component with Shape property set to one of the following values bsTopLine, bsBottomLine, bsLeftLine or bsRightLine depending on which line you currently need and resize it to a smaller size (in your case you can use bsTopLine or bsBottomLine and resize the bevel vertically):
Or you can use a special component called TDividerBevel which except the single line adds to this optical divider also a caption:
Here's what I've finally done but I'm not sure if this is the RIGHT way so I won't accept my answer. If there's someone else who can point out any issues with this, please let me know. I found this pretty straightforward as well :)
Place a TGroupBox on the form.
Leave the Caption property blank. Now it should look like a panel with only borders.
Use the mouse and drag the bottom border towards the top. Now it looks like a line.
Well, I personally think this method is NOT efficient as it would take up more memory space than just a real straight line. Anyway, so far it seems to work for me :)
Here's the screenshot - look towards the bottom (just above the last text box). The only issues is that on the sides of the line, it shows the lines bending. I think I should set the properties correctly than dragging with the mouse.
