QCAD has unexpectedly quit.

Please use the offscreen platform plugin for headless systems
(without a running X11 server):
./qcad -platform offscreen

In addition, you might have to override the default Qt style
to prevent the loading of a native desktop style (such as GTK):
./qcad -style plastique

I have tested this in version 3.22.1 too and get the same result. Reverting all the way back to 3.13.1 results in an operable version of qcad when working on the same file and library blocks.

 1615 QCAD (main)Bug ReportLow Decimal point of dimensions shown as '?', preferences p ...Closed
Task Description

First. I am not able to find OS selection for macOS Sierra so I choose Mac OS X.
I noticed that when I opened my drawing, I saw dimensions on drawing showed ‘156?6’ instead of ‘156.6’ in prior version I had installed. Probably in 3.16.5

So I opened Dimension Settings page to review and found when opening Dimension Settings under Drawing Preferences,
Dimension Settings does not show. It remains blank.

Then I clicked on other settings menu item from left and clicked back on the Dimension Settings I was able to see the Dimension setting.
However; when I closed the dialog and try to open the Dimension Settings again, I am not able to see the settings page at all. Just blank. I can see other settings page fine.

One time when I was able to see the Dimension Setting, I noticed that the Separator symbol was blank. So I updated that to ‘.’ and hit OK.
The drawing still shows ‘156?6’ instead of expected ‘156.6’.

It seems the separator symbol is not being saved for some reason.

 1568 QCAD (main)Bug ReportLow Issues: Snaps, Trim, Green selection tool Closed
Task Description


There is some issues with the snap tool and the selection tool.The trim button only trims some lines but not all.

1. The snap tool does not let me snap to certain things when i select something. For example i will select a box and i will try to extend the corner to another entities corner but the snap is not there so its free and thus not accurate.

2. For some reason the selection tool does not allow me to select certain things. If i have two boxes overlapping and i use the selection tool (from right to left “green selection box”) it does not allow me to select what i want i have to actually click it. This is annoying when it comes to selecting specific things.

3. The trim tool does not work properly.If i want to trim the inside of a cross hair or such, it only allows me to trim the inside of one line and if i try to trim the other it deletes the complete line.

Please fix as soon as possible. Thanks

 1525 QCAD (main)Bug ReportLow Block attributes: escaped unicode sequences in files no ...Closed
1 Task Description

The characters in Portuguese such as “ç é â ... etc ...” are replaced by codes starting with version 3.16.x
Files created with versions of QCAD 3.15.x whose characters were correct in the Properties List when opened by QCAD 3.15.x appear in this strange way when opened in versions 3.16.x.
However, in the screen and in the extraction of the list of attributes the characters are correct.
Apparently the error only occurs in texts on the Block Properties List and Attributes.
However, you can use correctly the characters in a file created from version 3.16.x

Exemplo: “dormitory’ in portuguese is “dormitório” it’s appear like “DORMIT\U+00d3RIO” when file is opened on QCAD 3.16.x

 1493 ECMAScriptBug ReportLow script processing failure using -exec Closed
Task Description

I have just updated from 3.11.0 to 3.15.5. Often, I load a script with the command format ..../qcad -exec ..../dims.js Note that the script filename is dims.

* Everything is satisfactory with 3.11.0 and always has been.

* qcad-3.15.5 runs satisfactorily without an -exec switch

* qcad-3.15.5 -exec same-file-as-for-3.11.0 crashes per the attached screenshot. The screenshot has been generated by adding the -enable-script-debugger switch.

* It appears that the script dims.js runs completely, and the crash happens as the script handler terminates. The qcad window is complete with the contents defined in dims.js, also qcad is usable normally. This qcad disappears when the debugger is terminated.

* This problem is totally repeatable.
