Stretch_height does not work within bootstrap

Hickson49Feb 14, 2021 #1

What are you trying to do?

Showing a bokeh plot inside a panel that is part of a bootstrap grid

What have you tried that did NOT work as expected?

p = figure(title=“Weather data”,
title_location=‘above’,
sizing_mode=“stretch_both”)

Basically the above abstract is working perfectly for width, but not a all for height, sizing_mode=“stretch_height” is of course not working either. Height of the plot always seems to be 600px whatever I do.
Here is a visual example:

I tried to provide a minimal working example, but this is quite complex due css dependencies. I am not looking for a direct solution, but mostly, a systematic approach to understand what is happening, and how this stretch_both option resuls in css with fixed values (I guess there is some js involved there, but it is not clear for me where I should look at).

Thank you in advance for your help.

Ok there seems to be some interesting js code to look for this specific issue in resize event listeners. Unfortunately, I just managed to go up to here:

github.com

bokeh/bokeh/blob/57edcf658e07138fb0e67b626efb28212e80354e/bokehjs/src/lib/models/layouts/layout_dom.ts#L59

    
      
            for (const child_view of this.child_views)
              child_view.remove()
            this._child_views.clear()
            super.remove()
          }
          
          
connect_signals(): void {
            super.connect_signals()
          
          
  if (this.is_root) {
              this._on_resize = () => this.resize_layout()
              window.addEventListener("resize", this._on_resize)
          
          
    this._parent_observer = setInterval(() => {
                const offset_parent = this.el.offsetParent
          
          
      if (this._offset_parent != offset_parent) {
                  this._offset_parent = offset_parent
          
          
        if (offset_parent != null) {
                    this.compute_viewport()

It is not clear for me where is resize_layout defined and how it relates to server side code defining stretch_both behaviour

@Hickson49 please state what version you are using, work on layout has been an ongoing activity under heavy development over many releases.

cc @mateusz do you have any input here?
