I am attempting to print a simple map from QGIS in portrait orientation. When I use the "Add New Map" tool it brings the map in at an extent which matches my original data frame if I were to use landscape orientation. See below:

However, when I set it to portrait, even if I do so before I add the map, it zooms out drastically and places my area of interest at the bottom end of the map.

Now, a bit of researching has revealed that I could zoom into the area I am interested in with my mouse's scroll wheel. However, my mouse does not have a scroll wheel. In addition, the Ctrl++ shortcut that works in the rest of QGIS does not work in Print Composer. Any help would be appreciated.

Heh, didn't mean to bring this question back to the front page by editing it, oh well. – jvangeld Jan 19 '12 at 22:25

I assume you're trying to zoom within the map frame, not zoom the composer itself (for which you use the magnifying glass buttons).

If you select the map frame and click the 'Item' tab, then the 'Extents' accordion, you can adjust the map extents. You can also use the 'Set to map canvas extent' to set it from the extents of the main QGIS window (roughly; if the canvas and the map frame have differing aspect ratios, the extents won't be exactly the same).

Awesome, that did it for me. It also helped me figure out how to change the text of a label. – jvangeld Jun 18 '11 at 4:16

You can also use the 'Move Item Content' button, which looks like this:

This will allow you to move the map frames contents without needing to go back to the map window. You can also zoom in and out with the scroll wheel (which unfortunately you don't have).

You can change the scale by selecting the item tab and altering the scale numerically.

That is a good reminder. I found that button already. – jvangeld Jun 21 '11 at 4:10
