UI Widgets for Blender 2.8

bl_ui_widgets's Issues

ModuleNotFoundError: No module named '__main__.drag_panel_op

Im not able to import the modules.

What cant i do?

please add more UI widget, such as InputBox\CheckBox

This project is amazing, using custom UI unit and OpenGL implement UI rather than the inner classes, like Panel\Menu.... This makes the UI more flexiable to creation. But the UI unit is not enough to use, lacking of InputBox\CheckBox\Dropdown\Table, etc. Hope you can realize these UI unit.

When switching from Blender to other applications the widgets with images in them will turn Black.

NVIDIA Geoforce 1060 GTX
Driver version 430.39

When switching from Blender to other applications the widgets with images in them will turn Black.

If you hit Ctrl-Shift-F again it fixes the images in the widgets.

Would be grateful for any ideas. Thank you.

Ability to disable/enable widgets

need to show/hide widgets during operator run, or be able to re-define the layout dynamically.

Resizing main blender window doesn't adjust the panel correctly.

When resizing Blender, the text inside the panel and buttons gets misaligned. The mouse hotspots also move along with it.

Would be great to leverage a resize window event to trigger a redraw?

StructRNA of type DP_OT_draw_operator has been removed - when swiching to a new scene

Hi,
After opening blender client, I install the widget and invoke it with Ctrl + Shift + k. Everything works fine, the widget displays and works. Then with the widget displayed I click New -> General -> Don't save. In the Console I get the following stack trace:

Then, in the new scene, when I press Ctrl + Shift + k, the widget displays, but in the consol window I get a continuous stream of errors exactly like above. Any idea how to fix this?

Ability to redefine layout on during modal

It would be great to re-define layout during execution, although it's possible that the new .visible property will be sufficient if it will work for e.g. a panel with children together.

Maximizing the area looses the connection

Simply hitting ctrl+space to maximize area throws error and causes the sampel widget operator to hang:
I think the library should store the link to areas differently (like indices or something), and should actively find a new area if it looses the original one, or end itself.

Mimic Blender's UI components and adopt themes colors

Hi Jayanam. I found your widgets so brilliant that I ended up making a fork of it with some additional features for my personal use. Now I've put together a full addon using the widgets and it works as expected. The few changes I did over your original code was to make the widgets mimic Blender's components and also to have them all follow the selected themes (in regards to colors, resolution scale etc). Thank you very much for creating this awesome UI and sharing it with the community. That is much appreciated. Everyone is welcome to take a look and try my fork at: githup.com/mmmrqs/bl_ui_widgets.

Below is a small image of how the sample panel appears on the viewport display.

All the best,
Marcelo

Deprecate in favor of the fork?

Hi Jayanam,

I've been using a modified version of bl_ui_widgets for years, and while looking to merge you recent edits I realized it was unmaintained and found this maintained fork: https://github.com/mmmrqs/bl_ui_widgets

Maybe this repo could be sunset in favor of that one or linked to it?

Thanks

Attempting to define multiple sliders confuses UI

her I defined 4 different sliders, mapped to different properties and added them to the widgets list. I epxected 4 sliders in a column. But instead all the sliders are on the same bar. I will dig into the panel setup code to understand how the sliders are populated.

Invoke widget when reloading scene

Hi, great tool. Instead of invoking the widget with a key combination I would like for it to happen whenever addon is loaded and I reload a scene. I tried to run it via Operator Search in the gui and by executing bpy.ops.object.dp_ot_draw_operator('EXEC_DEFAULT') in a persistent handler that I add in the register method - no success there. Any ideas? Thanks

Right click , middle click, mouse wheel , mouse move inputs

Generally, all mouse interactions would be great to have.

Mouse enter/exit functions

Disecting what I tried to commit in the pull requests to a few needed functions.

-Need to call these to draw a tooltip or call own functions on entering elements.

-Also would be great to be able to parse keyboard shortcuts - on_keystroke or similar in modal function.

Further needed functions are actually for all mouse interactions - mouse wheel, right-click .

Images turn black if the interaction doesn't happen for some time

The images drawn still need glTouch() or some other solution to not turn black. An issue was posted for it but was closed.

Button image upper right corner has wrong coordinates. (with solution)

bl_ui_button.py - from line 88 should be:

vertices = (
(self.x_screen + off_x, y_screen_flip - off_y),
(self.x_screen + off_x, y_screen_flip - sy - off_y),
(self.x_screen + off_x + sx, y_screen_flip - sy - off_y),
(self.x_screen + off_x + sx, y_screen_flip - off_y))

Currently there's a - off_x on the last coorinate Y which draws the corner offset on non-square offset values.

visible property should work on children widgets

It would be more convenient and logical if you set .visible for a panel if it would hide all children widgets
