The help file states somewhat confusingly:

I have corrected the help file but this is probably not in time for the next release.

ClearWin+ does not currently provide a simple way to get the current size of a given panel in the status bar.

The information is available via a call to SendMessage by using the HWND of the status bar and SB_GETRECT. If you want to try this then the first step would be to test to see if %lc works for %sb.

Paul,

Thanks. SET_STATUS_TEXT@ doesn't appear to be in the Library Reference either.

When is the next version due?

We are working on it right now.

Paul,

I followed up the suggestion, and it isn't a lot of help. I came across SBARS_SIZEGRIP - that is something that puts the sizing icon in the bottom rhs of the window. Aesthetically, when the client area extends to the bottom of the window, the window looks a bit unbalanced, and even when a status bar is in use, (because everything is clustered to the left), the 'size-grip' is a nice feature, even if it is rather obsolete as all window edges are resizable these days.

I also saw that the status bar can have tooltips. My suggestion is therefore for:

%sb[sizegrip][tooltips]

I'm not much of a fan of straying outside Clearwin+, as you probably guessed.

I probably didn't express myself well in the original post. What I really want to do is find out how much capacity the status bar has before I invoke winio@('%sb so that I don't simply program invisible stuff off the end. I know this will be wrong for different logical dpi settings, so it will need to be assessed conservatively. Perhaps it's a question of running some tests and measuring using my onscreen pixel ruler: 'RulerByGeorge!'

Eddie

PS. Just about everything I write is run fullscreen, because the maximum number of pixels is required for the best graphical interaction.

I have made a note of your request/suggestion.

Paul,

Many thanks for considering this.

I've done some measurements, and with a standard dpi setting, the text typically has a length that equates to about 5.3 pixels per character.

I run a dual monitor setup, with two 1920x1080 screens side by side. When my app with a %sb is launched, the statusbar doesn't have a 'sizegrip' If I move the window to straddle the two monitors, the window extends laterally, and the status bar then shows a 'sizegrip', which then remains part of it even if the window is shrunk back to fit on one screen. Weird.

I have had a look at this.

SBARS_SIZEGRIP does not appear to do anything useful. If the window can be resize then you get the gripper anyway. If the window can't be resized then SBARS_SIZEGRIP adds the gripper but you can't use it to resize the window.

I will see if anything can be done with tooltips.

The SBARS_TOOLTIPS style is rather limited. Its purpose is to provide a tooltip for when the text is too long to fit into the pane. When the pane is big enough the tooltip does not appear. The tooltip is simply a copy of the text in the pane and the user sets this by calling set_status_text@.

This will probably not work with the first pane and %`sb where menu item info is controlling the content of the pane.

I have added this style but it may not be of much interest to users.

Hi Paul,

Thanks for looking at this.

I don't know. It's all in the Windows API.

PaulLaidler · Posted: Fri May 03, 2019 3:52 pm Post subject:

If I wanted to know if a string will appear without truncation within a pane then I would do something like...

1) get the width of the pane via SendMessage and SB_GETRECT,

2) get the device context of the status bar using GetDC,

3) get the width of the text I want to display via GetTextExtentPoint32,

4) test if the text width is <= the pane width.

You can probably do this in Fortran but it's a lot easier in C.

Can anyone else help John with the details?
